I'm trying to create a script to copy a secure exe file to the C directory from a flash drive that is assigned the drive letter D. Then to run the exe, delete the exe, then shut down the PC. I have technicians who need to do this in order to make a biometric reader function properly. They keep screwing up the process and I would like to automate the process to save me a headache. The file is secure and cannot be leaked to our customers due to licensing. I already tried a batch script, but the exe doesn't seem to launch correctly.
Here's what I had:
COPY "D:\Biometric\software.exe" "C:\software.exe"
Pause
pushd C:\
Start "C:\software.exe"
Pause
pushd C:\
erase "software.exe" /F /Q
Pause
c:\windows\system32\shutdown -s -f -t 00
I've never tried VBScript, and I figured maybe that might get me the results I need, any help would be appreciated.
Start considers the first set of quotes it finds to be the window's title, so what you have in your code essentially says "set the window's title to 'C:\software.exe' and then execute the start command on nothing."
Insert an extra set of quotes to make the start command work.
start "" "C:\software.exe"
We need to disconnect and re-map a network drive on Windows 7, using a set of scripts (or an app) that runs off the same network path.
That is, I need something that loads itself into RAM before it runs, so it continues to run after the drive is disconnected.
Any ideas?
Please note that 16-bit apps are NOT supported in 64 bit systems (this explains why the Novell utility failed).
You would need a vbs file running throughout a logon session to remap drives if it's disconnected by user. Need to make this script to run when domain user logs on - e.g. Logon Script in AD or GPO. There are many ways to do it.
You could even disable "Remove Network drives" feature from Explorer GUI via GPO or Reg key (net use command still works).
Or you can tweak solution by Julius for this SO question to fit your need. But consider performance impact of the vbs - only check every n minute(s) in an infinite loop.
We do something similar. We have a batch file on the network that maps the drives a user needs. We update the batch file from time to time, and users run it from a shortcut that we've placed on their desktop:
C:\WINDOWS\system32\cmd.exe /c (#echo off&if not exist \\172.x.x.x\Login (echo Unable to access server&pause) else (md c:\TMP > NUL 2>&1 © \\172.x.x.x\Login\MapDrives.bat C:\TMP /y > NUL 2>&1 &call C:\TMP\MapDrives.bat&del C:\TMP\MapDrives.bat&rd c:\TMP))
You can see that it checks to see if they can access the server, and if they can, it creates a folder C:\TMP, copies the MapDrives.bat file locally, then runs it. Since it is running locally, it can remap network drives without terminating it own execution. And we can update the batch file on the server without pushing it to each user's computer.
If you don't want to create a shortcut with the long command line above, it might work to create a second batch file on the server (e.g., RunMe.bat) that users run from the server. You could place all of the code from the shortcut in the RunMe.bat and accomplish the same thing. Of course, you'd want to add one more line of code to change to the local drive (so Windows doesn't hold open a handle to the network drive). Something like this:
#echo off
C:
if not exist \\172.x.x.x\Login\MapDrives.bat (
echo Unable to access server
pause
) else (
md c:\TMP > NUL 2>&1
copy \\172.x.x.x1\Login\MapDrives.bat C:\TMP /y > NUL 2>&1
C:\TMP\MapDrives.bat
)
I kept the if not exist ... because you might place the RunMe.bat in a different location than the MapDrives.bat, so it still makes sense to verify the user can access the file. Because I didn't use call C:\TMP\MapDrives.bat, it transfers control to the local batch file and any handles to the server should be closed so the drive can be remapped. This means however, that you cannot place more commands after the C:\TMP\MapDrives.bat command.
I am trying to run a batch file from a network share, but I keep getting the following message: "UNC path are not supported. Defaulting to Windows directory." The batch file is located on \\Server\Soft\WPX5\install.bat. While logged in as administrator, from my Windows 7 Desktop, I navigate to \\Server\Soft\WP15\ and double click on install.bat, that's when I get the "UNC path are not supported." message. I found some suggestions online stating that mapping drive will not work, but using a symbolic link will solve this issue, but the symbolic link didn't work for me. Below is my batch file content, I would appreciate any assistance that can help me accomplish what I am trying to do. Basically, I want to be able to run the batch file from \\Server\Soft\WP15\install.bat.
Batch file content
mklink /d %userprofile%\Desktop\WP15 \\server\soft\WP15
\\server\soft\WP15\setup.exe
robocopy.exe "\\server\soft\WP15\Custom" /copyall "C:\Program Files (x86)\WP\Custom Templates"
Regedit.exe /s \\server\soft\WPX5\Custom\Migrate.reg
Also, how do I remove the symbolic link after the install is completed?
PUSHD and POPD should help in your case.
#echo off
:: Create a temporary drive letter mapped to your UNC root location
:: and effectively CD to that location
pushd \\server\soft
:: Do your work
WP15\setup.exe
robocopy.exe "WP15\Custom" /copyall "C:\Program Files (x86)\WP\Custom Templates"
Regedit.exe /s WPX5\Custom\Migrate.reg
:: Remove the temporary drive letter and return to your original location
popd
Type PUSHD /? from the command line for more information.
I feel cls is the best answer. It hides the UNC message before anyone can see it. I combined it with a #pushd %~dp0 right after so that it would seem like opening the script and map the location in one step, thus preventing further UNC issues.
cls
#pushd %~dp0
:::::::::::::::::::
:: your script code here
:::::::::::::::::::
#popd
Notes:
pushd will change your working directory to the scripts location in the new mapped drive.
popd at the end, to clean up the mapped drive.
There's a registry setting to avoid this security check (use it at your own risks, though):
Under the registry path
HKEY_CURRENT_USER
\Software
\Microsoft
\Command Processor
add the value DisableUNCCheck REG_DWORD and set the value to 0 x 1
(Hex).
Note:
On Windows 10 version 1803, the setting seems to be located under HKLM:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor
Basically, you can't run it from a UNC path without seeing that message.
What I usually do is just put a CLS at the top of the script so I don't have to see that message. Then, specify the full path to files in the network share that you need to use.
I needed to be able to just Windows Explorer browse through the server share, then double-click launch the batch file. #dbenham led me to an easier solution for my scenario (without the popd worries):
:: Capture UNC or mapped-drive path script was launched from
set NetPath=%~dp0
:: Assumes that setup.exe is in the same UNC path
%NetPath%setup.exe
:: Note that NetPath has a trailing backslash ("\")
robocopy.exe "%NetPath%Custom" /copyall "C:\Program Files (x86)\WP\Custom Templates"
Regedit.exe /s %NetPath%..\WPX5\Custom\Migrate.reg
:: I am not sure if WPX5 was typo, so use ".." for parent directory
set NetPath=
pause
Instead of launching the batch directly from explorer - create a shortcut to the batch and set the starting directory in the properties of the shortcut to a local path like %TEMP% or something.
To delete the symbolic link, use the rmdir command.
I ran into the same issue recently working with a batch file on a network share drive in Windows 7.
Another way that worked for me was to map the server to a drive through Windows Explorer: Tools -> Map network drive. Give it a drive letter and folder path to \yourserver. Since I work with the network share often mapping to it makes it more convenient, and it resolved the “UNC path are not supported” error.
My situation is just a little different. I'm running a batch file on startup to distribute the latest version of internal business applications.
In this situation I'm using the Windows Registry Run Key with the following string
cmd /c copy \\serverName\SharedFolder\startup7.bat %USERPROFILE% & %USERPROFILE%\startup7.bat
This runs two commands on startup in the correct sequence. First copying the batch file locally to a directory the user has permission to. Then executing the same batch file. I can create a local directory c:\InternalApps and copy all of the files from the network.
This is probably too late to solve the original poster's question but it may help someone else.
This is the RegKey I used:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor]
"DisableUNCCheck"=dword:00000001
My env windows10 2019 lts version and I add this two binray data ,fix this error
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor DisableUNCCheck value 1
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Command Processor
DisableUNCCheck value 1
This is a very old thread, but I still use Windows 7. :-)
There is one point that no one seems to have taken into account, which probably would help Windows 10 users also.
If Command Extensions are enabled, the PUSHD command accepts network paths in addition to the normal drive letter and path.
So the obvious - and simplest - answer might be to enable command extensions in the batch script, if you intend to use PUSHD. At the very least, this ought to reduce the problems you might have in using PUSHD wqith a network path.
I stumbled upon this question while searching for a solution to a specific problem. I needed to make a batch script that sits in a network folder (UNC path) with a Python script. The goal was to be able to double click on the batch script and have it run the Python script:
with the network folder containing the script as the working directory,
without modifications to the Python script (no command line parameters or hard-coded paths).
without creating another Python file.
The pushd and popd solutions were unsatisfactory. They work, but if the user were to get in the habit of forcefully terminating the script while it was running, they would end up with a bunch of mapped drives in My Computer since popd wasn't run.
I start by using cls to clear the UNC path error. I then assign the path containing the batch script to a variable. I slice the path to remove the trailing backslash (otherwise, Python throws a SyntaxError). Finally, I run a couple Python commands inside the batch file that change the working directory and execute the target script:
cls
#echo off
set pyfile=myscript.py
set batchdir=%~dp0
set wdir=%batchdir:~0,-1%
python -c "import os; import runpy; os.chdir(r""%wdir%""); runpy.run_path(r""%pyfile%"")"
pause
Editing Windows registries is not worth it and not safe, use Map network drive and load the network share as if it's loaded from one of your local drives.
I would like to know what are the approaches that you use to manage the executables in your system. For example I have almost everything accessible through the command line, but now I come to the limit of the path string, so i can't add any more dir.
So what do you recommend?
A long time ago, I tried to use softLinks of the executables in a Dir that belonged to the path, but that approach didn't work.
Throw the "executable only" to a known Dir,has the problems that almost any application require a set of files, so this also is bad.
Throw the executable and all his files to a known Dir, mmm this will work, but the possibility to get a conflict in the name of the files is very very high.
Create a HardLink? i don't know. What do you think?
This will parse your %PATH% environment variable and convert each directory to its shortname equivalent and then piece it all back together:
#echo off
SET MyPath=%PATH%
echo %MyPath%
echo --
setlocal EnableDelayedExpansion
SET TempPath="%MyPath:;=";"%"
SET var=
FOR %%a IN (%TempPath%) DO (
IF exist %%~sa (
SET "var=!var!;%%~sa"
) ELSE (
echo %%a does not exist
)
)
echo --
echo !var:~1!
Take the output and update the PATH variable in environment variables.
One way I can think of is to use other environment variables to store partial paths; for example, if you have
C:\this_is_a\long_path\that_appears\in_multiple_places\subdir1;
C:\this_is_a\long_path\that_appears\in_multiple_places\subdir2;
then you can create a new environment variable such as
SET P1=C:\this_is_a\long_path\that_appears\in_multiple_places
after which your original paths become
%P1%\subdir1;
%P1%\subdir2;
EDIT: Another option is to create a bin directory that holds .bat files that point to the appropriate .exe files.
EDIT 2: Ben Voigt's comment to another answer mentions that using other environment variables as suggested might not reduce the length of %PATH% because they would be expanded prior to being stored. This may be true and I have not tested for it. Another option though is to use 8dot3 forms for longer directory names, for example C:\Program Files is typically equivalent to C:\PROGRA~1. You can use dir /x to see the shorter names.
EDIT 3: This simple test leads me to believe Ben Voigt is right.
set test1=hello
set test2=%test1%hello
set test1=bye
echo %test2%
At the end of this, you see output hellohello rather than byehello.
EDIT 4: In case you decide to use batch files to eliminate certain paths from %PATH%, you might be concerned about how to pass on arguments from your batch file to your executable such that the process is transparent (i.e., you won't notice any difference between calling the batch file and calling the executable). I don't have a whole lot of experience writing batch files, but this seems to work fine.
#echo off
rem This batch file points to an executable of the same name
rem that is located in another directory. Specify the directory
rem here:
set actualdir=c:\this_is\an_example_path
rem You do not need to change anything that follows.
set actualfile=%0
set args=%1
:beginloop
if "%1" == "" goto endloop
shift
set args=%args% %1
goto beginloop
:endloop
%actualdir%\%actualfile% %args%
As a general rule, you should be careful about running batch files from the internet, since you can do all sorts of things with batch files such as formatting your hard drive. If you don't trust the code above (which I wrote), you can test it by replacing the line
%actualdir%\%actualfile% %args%
with
echo %actualdir%\%actualfile% %args%
Ideally you should know exactly what every line does before you run it.
if you are using windows vista or higher, you can make a symbolic link to the folder. for example:
mklink /d C:\pf "C:\Program Files"
would make a link so c:\pf would be your program files folder. I shaved off 300 characters from my path by using this trick.
In case anyone's interested...
I find I never really need all those paths at once, so I create a bunch of "initialization" batch files which modify the path accordingly.
For example, if I wanted to do some C++ development in Eclipse, I would do:
> initmingw
> initeclipse
> eclipse
This is also handy for avoiding conflicts between executables with the same name (such as the C++ and D compilers, which both have a make.exe).
My batch files typically look like this:
#echo off
set PATH=C:\Path\To\My\Stuff1;%PATH%
set PATH=C:\Path\To\My\Stuff2;%PATH%
I find this approach relatively clean and have yet to run into any problems with it.
I generally don't have to worry about this (I haven't run into a path size limit - I don't even know what that is on modern Windows systems), but here's what I might do to avoid putting a program's directory in the path:
most command line utilities get thrown into a c:\util directory that's on the path
otherwise, I'll add a simple cmd/batch file to the c:\util directory that looks something like:
#"c:\program files\whereever\foo.exe" %*
which essentially creates an alias for the command. It's not necessarily perfect. Some programs really insist on being in the path (that's pretty rare nowadays), and other programs that try to invoke it might not find it properly. But for most uses it works well.
But generally, I haven't had to worry about avoiding adding directories to the path.
Another idea: Use DIR /X to determine the short names generated for non-8dot3 file
names. Then use these in your %PATH%.
For example, 'C:\Program Files' becomes 'C:\PROGRA~1'.
USe the App Path registry key instead of the path variable for application-specific paths:
http://msdn.microsoft.com/en-us/library/windows/desktop/ee872121(v=vs.85).aspx
I wrote and use on a every-time basis a standard stream (stdin/stderr/stdout) & exit code PROXY program (called dispatcher https://github.com/131/dispatcher)
All CLI program i use (node, php, python, git, svn, rsync, plink ...) i'm using are actually the same exe file (around 10kb, that i just name differently), that i put in the same directory. A dummy static clear text file do the "proxy file name to real exe mapping".
Dispatcher use low level Process management win32 API to be absolutly transparent.
Using this software, i only do have ONE additionnal directory set in my PATH for all programs i might use.
Creating a folder c:\bin adding to your path and hardlinking like you said could shorten the string. Maybe add a variable pf to system vars with value c:\Program Files then replace c:\Program Files with %pf% in path.
Edit:
Create a virtual drive.
subst p: "c:\program files"
I follow these steps to make the entries manageable:
Created different users for different combination of software packages usage.
Example: (a) Created a user web for making available all the web development software; (b) Created a user database for making available all the database and data warehousing software packages. Remember some software may create more than one entry. Or sometime I break this into oracle specific and MSSQL specific and oracle specific users. I put MySQL/PostgreSQL, tomcat, wamp, xamp all into the user account webr.
If possible install common packages like office, photoshop, .. as system specific available for all users and special packages as user specific. Of course I had to log into different users and install them. Not all software may provide this option. If "install for this user only" option is not available, install it for the whole system.
I avoid installing programs in to the folder Program File (x86) or in to Program File. I always install into the base directory. For example MySQL 64 bit goes into "C:\mysql64" and MySQL 32 bit goes into "C:\mysql" folder. I always assume adding a suffix 64 only for 64bit software. If no suffix, then it is a 32 bit. I follow the same thing to Java and others. This way my path will be shorter, not including "C:\Program File (x86)". For some software the configuration file may need to be edited to show where exactly the .exe file is. Only program that demands to be installed into "C:\Program File (x86)" will be installed into that folder. Always I remember to shorten the names. I avoid version number like tomcat/release/version-2.5.0.3 such details. If I need to the know version, I create a file by name version and put it into the tomcat folder. In general shorten the link as much as possible.
Include any batch to replace abbreviated link to the path, if all the above steps passed the Windows limit.
Then Log into usage specific (mobile application, or database/data warehousing or web-development.. ..) user and do the relevant tasks.
You can also create virtual windows within windows. As long as you have one licensed OS copy, creating multiple virtual windows with same key is possible. You can put packages specific for a particular task in that machine. You have to launch separate VM each time. Some memory intensive packages like 3D animation movie makers all should be put into the main machine, not into VM as VM will have only a part of the RAM available for its use. It is a pain to boot each VM though.
The solutions above only work if you can trim down your path. In my case, that wasn't really an option, and it was a hassle to have to run a script every time I opened a command prompt. So I wrote a simple script that runs automatically when opening the command prompt, and appends the contents of a text file to your path.
There are also some contexts where having this script run breaks things (say, in a github or cygwin shell), so I also added a file that contains a list of paths that, if the command prompt is started in them, the path variable isn't changed via the startup script that normally updates the path.
#echo off
:: Modify these to the actual paths of these two files
set dontSetupFile=C:\Users\Yams\Dontsetup.txt
set pathFile=C:\Users\Yams\Path.txt
:: Retrieve the current path (for determining whether or not we should append to our path)
set curDir=%cd%
:: Be done if the current path is listed in the dontSetupFile
SetLocal EnableDelayedExpansion
for /F "delims=" %%i in (%dontSetupFile%) do (
if "%%i"=="%curDir%" GOTO AllDone
)
:: Append the pathFile to our current PATH
set pathAppend=
for /F "delims=" %%i in (%pathFile%) do (set pathAppend=!pathAppend!%%i)
set PATH=%PATH%;%pathAppend%
:: The only way to actually modify a command prompt's path via a batch file is by starting
:: up another command prompt window. So we will do this, however, if this script is
:: automatically called on startup of any command prompt window, it will infinately
:: recurse and bad things will happen.
:: If we already ran, we are done
if "%yams%"=="onion" GOTO AllDone
:: Otherwise, flag that we just ran, and then start up a new command prompt window
:: with this flag set
set yams=onion
cmd \K set PATH=%PATH%;
:: When that command prompt exits, it will load back up this command prompt window, and
:: then the user will need to exit out of this as well. This causes this window to
:: automatically exit once the cmd it just spawned is closed.
exit()
:: Path is set up, we are done!
:AllDone
#echo on
And Path.txt will look something like
C:\Program Files (x86)\Google\google_appengine;
C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;
C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;
C:\Program Files\Microsoft SQL Server\110\Tools\Binn;
C:\Program Files\Microsoft DNX\Dnvm;
C:\Program Files (x86)\Windows Kits\8.0\Windows Performance Toolkit;
While Dontsetup.txt will look something like
C:\Program Files (x86)\Windows Kits\8.0\Windows Performance Toolkit
C:\Program Files (x86)\Git\cmd
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin
To make this run automatically on startup, open regedit, navigate to HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Command Processor, then right click on the right and press new -> Multi-String Value. Name it AutoRun. Set it's value to
C:\Users\Yams\setUpPath.bat
or wherever else you stored the batch file above.
Didn't try it, but will splitting PATH in parts work and joining them in final variable work?
Example initially let's say you have something like
PATH={LONGPATH1};{LONGPATH2};....{2048th char}....{LONGPATH_N-1};{LONGPATH_N}
Instead you create:
_PATH1 = {LONGPATH1};{LONGPATH2};....{2048 char}
_PATH2 = {2049th char}...{LONGPATH_N-1};{LONGPATH_N}
rem // may be more parts
PATH = %_PATH1%;%_PATH2%
I got some folders created by malware whose name ended with a dot like C:\a.\ or C:\b.\, etc.
I found a solution that can remove such folder with command rd /q /s "C:\a.\" but if I call win API RemoveDirectory, it returns ERROR_FILE_NOT_FOUND.
And I just wonder how to write a function to delete such directory, thanks
I test on my own Windows XP SP3 system like this
create a folder C:\>mkdir a..\\\ and I cannot double click to access this folder. and I can remove with command rd /q /s "C:\a.\"
what Windows system API(s) that rd /q /s command call?
Here's a solution to this problem:
rd /s "\\?\C:\Documents and Settings\User\Desktop\Annoying Folder."
Solution:
When you call RemoveDirectory, make sure that you prefix the path with the string "\\?\".
Explanation:
It has everything to do with the dot. According to MSDN, there are certain cases where you may not be able to delete a file or folder on an NTFS volume, specifically when the file name is invalid in the Win32 name space (which is why you are unable to open the file using the normal methods in Windows Explorer).
You may not be able to delete a file if the file name includes an invalid name (for example, the file name has a trailing space or a trailing period or the file name is made up of a space only). To resolve this issue, use a tool that uses the appropriate internal syntax to delete the file. You can use the "\\?\" syntax with some tools to operate on these files, for example:
del "\\?\c:\path_to_file_that contains a trailing space.txt "
The cause of this issue is similar to Cause 4. However, if you use typical Win32 syntax to open a file that has trailing spaces or trailing periods in its name, the trailing spaces or periods are stripped before the actual file is opened. Therefore, if you have two files in the same folder named "AFile.txt" and "AFile.txt " (note the space after the file name), if you try to open the second file by using standard Win32 calls, you open the first file instead. Similarly, if you have a file whose name is just " " (a space character) and you try to open it by using standard Win32 calls, you open the file's parent folder instead. In this situation, if you try to change security settings on these files, you either may not be able to do this or you may unexpectedly change the settings on different files. If this behavior occurs, you may think that you have permission to a file that actually has a restrictive ACL.

Ive posted this on SU and I decided to post it here too. Its the simplest and fastest and easiest way to achieve this. I am now laughing at how much simple it is.
Install WinRAR
Follow the Step by Step procedure from pictures:
I myself had WinRaR installed so I decided to demonstrate the workaround in it.
This workaround is also possible by using 7zip.
One another thing I should mention is that, as it seems the problem is caused by using windows explorer and any other file browser (like winrar file browser itself, ftp explorers etc.) will treat this files as normal.
You could try using any file browser and simply delete those files and not bother archiving them though!
Cheers!
If you have git installed (you can get ir from here) then it is as simple as:
Navigate File Explorer to location where problematic folder is located.
Context menu (right mouse button) > Git Bash Here.
rm -rf Foldername./
When you see the name is "a.", but the actual name is "a.."
Try this:
rd /q /s "C:\a..\"
And you can try explore the folder by this code:
for /f "tokens=3 delims=<>" %%a in ('dir /ad /x "C:\*" ^| findstr " a\.\.$"') do (
for /f "tokens=1" %%b in ("%%a") do start "" "%%~fb"
)
I used "WinRar" A simple RAR, ZIP processor. You can use any sort of file name editor. Just open the directory where your file is into WinRar and select rename after right clicking the file/folder you want to rename and fill in the new name.
If you need to keep the data you can also use the \\?\ trick for renaming the folder.
ren "\\?\C:\Documents and Settings\User\Desktop\Annoying Folder." "\\?\C:\Documents and Settings\User\Desktop\Annoying Folder"
This is an ideal solution if you need to know what is inside the folder or if the data is important.
This works in both Command Prompt and PowerShell.
Try to use unlocker program to delete files and folders that you can't delete normally.
if you want to keep the files theres options in bash as well.
you will require the Windows Subsystem for Linux package (i have Ubuntu installed)
to keep the files. open a command prompt and cd over to where the file or folder is located.
now type "bash"
this will open bash in the prompt. now enter mv '[folder or file you want to move]' '[new name (can include path)]' (theres more to mv so if you want to read up on all of its options use 'man mv' this will open its manual page (then use q to return to bash))
the mv command is short for move, but its has a secondary function of renaming things.
also in bash use 'single quotes' and not a normal "double quote", as bash expects 'single quotes'.
heres a example. assume your folder is named "data 1." located in c:\users (so the full path to the error folder is c:\users\data 1.
1. open command prompt using any method
2. enter cd c:\users
3. now type bash this loads bash in the folder you previously were in
4. finally type mv 'data 1.' 'data 1'
5. the folder is now accessible and you can choose to delete it.
Use bash rm command from Ubuntu on Windows 10
