Ruby can not delete file after cp on windows - ruby

I am using rake to copy files I receive from one folder to two sub-folders.
After the copy I try to delete these files from their original folder.
I can't seem to delete some of the files (usually only 1 or 2 out of 5 or so).
When using mv (and not CLEAN) I receive an error message of access denied.
I believe that Windows (my OS) still holds a reference to the file/s and therefore won't
allow me to delete them.
I can delete the files out of code no problem. There should not be a permissions issue.
If my theory is correct that there is still a reference open to the file, then how could i close those references?
Could it be something else?
The code:
DOCK = '/path'
NEW_FILES = DOCK + '/NewFiles'
dock_stock = FileList.new(DOCK + '/*.xml')
file target_path do |t|
unless dock_stock.empty?
mkdir t.name
dock_stock.each do |f|
target_new_files_folder = f.pathmap(NEW_FILES + '/%f')
mv f, target_new_files_folder
end
end
end
Also it should be noted this task is a dependency to a multitask(really a dependency of a dependency of a dependency). task :clean => target_path being one of them.
So maybe the issue is multi thread related or the :clean task.

It seems there was a McAfee Agent that was referencing the files not allowing me to delete them.
For the most part, if I tried to delete them later on in time they would delete.
When I write for the most part I mean once in a blue moon it could hold the files for days until released manually.
The workaround would be to record the problematic files and exclude them from the file list and try to erase them at a later point.
Wish I had a better solution.

The windows del command has f option, which forces the deletion. Combine with /q(uite) and run it from Ruby with for instanceexec:
exec 'del /f /q filename'

Delete all files except those with a specific extension in VBS [duplicate]

I'm making a project out of creating a script to use at work to automate one of our processes.
I'd like the script to check an input for username to search the specified user profile path for any files of .doc,.docx,.pdf,.pst ect. and copy them as is to a created folder on a network drive location.
My main question is what is the command or chain of commands to check folders and sub folders starting at the specified userpath, for JUST files with those extensions and I guess copy them but without getting to a situation where it just copies the same file over and over and over again. Sorry if that's confusing.
This answer provides sample code for recursively traversing a folder tree. A list of extensions could be handled by creating a dictionary:
Set extensions = CreateObject("Scripting.Dictionary")
extensions.CompareMode = vbTextCompare 'case-insensitive
extensions.Add "doc", True
extensions.Add "docx", True
extensions.Add "pdf", True
extensions.Add "pst", True
...
and then checking the extension of the processed files like this:
For Each f In fldr.Files
If extensions.Exists(objFso.GetExtensionName(f.Name)) Then
f.Copy targetFolder & "\"
End If
Next
The trailing backslash is required when the destination is a folder, otherwise you'd have to specify the full target path including the target filename.
I think I have understood most of the requirements, and this can be more easily achieved by using a .BAT file approach within windows. This batch (.Bat) file can run commands such as copy / delete etc.
So create a file called test.bat, and inside the file add the below script:
::XCOPY source [destination]
XCOPY "C:\Temp\*.doc" "C:\Temp\another"
What does this do? Well it uses an XCOPY Command to copy any files within the C:\Temp direcory which have a .doc extension. The files will be copied over to a folder called C:\Temp\another.
The XCOPY takes two primary arguments: source and destination. Source is where the file currently lives, and destination is where you want to copy the files to. More info of all of the options available can be found on:
http://support.microsoft.com/kb/240268
In order to run the file, just double click it, or schedule it to run whenever required.
Let me know if this meets your requirement, I didn't fully understand the bit about an input for a username?

Windows 7 Folder broken creation glitch

I wrote a program in python that created folders. I'm having difficulty removing some of the folders due to this glitch.
I already figured out how to prevent it. But for the folders already created are irremovable. I get this error message when trying to delete them.
Could not find this item. This is no longer located at ... Verify the items location and try again [Try Again][Cancel]
I tried removing the folders by typing dir /x into a console
and then using the shorthand of the folder name with the del program. ex: del FOLDER~1
But that only works some of the time.
The only difference between the broken and non broken folders is the space at the end of the folder name when creating.
How to make a broken directory:
mkdir "broken folder /"
How to make a normal directory
mkdir "normal folder/"
Extra info:
The folders can still be used. The files inside can be deleted. Just not the folder itself or its parent folder.
When this glitch occurs in python using os.mkdir it also creates two directories with the exact same name. Only one can be deleted regularly.
I wrote a python script that fixes all the broken folders. So if anyone hits this issue. Hope this helps. Just drop into whatever folder is full of broken folders. Its kind of poorly made. But gives an idea about what you need to do.
from glob2 import glob
import os
import shutil
#find all folders
folders = glob("./**/")
# for each folder check if they exist and rename them to have an A at the end of their name.
for fold in folders:
if fold != ".\\":
if os.path.exists(fold):
name = fold.rsplit("\\", 2)[-2] + "A"
print(name)
print(fold)
os.rename(fold, name)

VBS Script to locate all files of certain extensions and copy them to a specific destination

Excluding folders in Winrar

A Day with Winrar
All I wanted to do was exclude folders and their contents using wildcards, and even after reading the docs, it turned into a guessing game...
So my test bed looks like:
C:\!tmp1\f1
C:\!tmp1\f1\f1.txt
C:\!tmp1\f1\a
C:\!tmp1\f1\a\a.txt
C:\!tmp1\f2
C:\!tmp1\f2\f2.txt
C:\!tmp1\f2\a
C:\!tmp1\f2\a\a.txt
And I am executing:
C:\>"c:\program files\winrar\winrar.exe" a -r !tmp1.rar !tmp1
which gives me a rar with !tmp1 as the root (sole top level folder).
The exclude switch is -x<filepathpattern> and may be included multiple times.
So, given that we want to exclude f2, and all its subcontents...
-x*\f2\*
removes the contents, but leaves f2
-xf2
does nothing - includes all
-x\f2
does nothing - includes all
-x*\f2
does nothing - includes all (now I'm mad), so surely it must be..
-x\f2\
nope, does nothing - includes all. So it has GOT to be...
-x*\f2\
hell no, does nothing - includes all. and I already know that
-x*\f2\*
removes the contents, but leaves f2. Onward we go...
-x*f2\
does nothing - includes all. Grrrr. Aha! how about...
-x!tmp1\f2\
nope, does nothing - includes all. WTF. Alright, So it has GOT to be...
-x!tmp1\f2
Holy moly, it worked! Hmmm, then how come....
-x*\f2
does not work? This was the little demon that sent me down this crazed path to begin with and should have worked!
Given all that, do I dare try to go after */a/* directories, removing contents and the dirs?
-x*\a
does not work, of course, does nothing.
-x*\*\a
does not work, of course, does nothing.
-x!tmp1\*\a
nope. But...
-x*\a\*
removes contents of both dirs, but leaves the folders. So, in desperation I can use the -ed switch which will not store empty folders, but this is a broad hack, I want to eliminate the folders specified not all empty folders.
With my animosity growing toward winrar, I am passing the baton of information forward with an eye to that glorious day when we will know how to specifically exclude a folder and its contents using wildcards and not using the -ed switch.
(Quite old question but still may be relevant)
Maybe what you simply needed was this :
-x*\f2 -x*\f2\*
two exclude switches, should remove directory f2 and all its contents.
An even older question by now, but came across this question so I reproduced your folder structure and, at least nowadays (Winrar 5.11, not the latest but quite new), this works:
-x*\f2
So the whole command line is:
"C:\Program Files\WinRAR\Rar.exe" a -m5 -s !tmp1.rar !tmp1 -x*\f2
And this is what is stored in the .rar file:
!tmp1\f1\a\a.txt
!tmp1\f1\f1.txt
!tmp1\f1\a
!tmp1\f1
!tmp1
Similarly, if you use -x*\a, all a folders are excluded, storing this:
!tmp1\f1\f1.txt
!tmp1\f2\f2.txt
!tmp1\f1
!tmp1\f2
!tmp1
Finally, combining both parameters (-x*\f2 -x*\a), you get this:
!tmp1\f1\f1.txt
!tmp1\f1
!tmp1
To manage large list of files to be excluded, you can create text fie and write all excluded files/folders relative to the source folder:
1) create file list.txt, write the name of excluded files/folders
note: * refer to the source, all files/folders are relative to the source folder
*\f2
*\f3
2) Run the command
rar a -r -x#list.txt target.rar source-folder

Directory dependencies with rake

I'm using rake to copy a directory as so:
file copied_directory => original_directory do
#copy directory
end
This works fine, except when something inside of original_directory changes. The problem is that the mod date doesn't change on the enclosing directory, so rake doesn't know to copy the directory again. Is there any way to handle this? Unfortunately my current setup does not allow me to set up individual dependencies for each individual file inside of original_directory.
You could use rsync to keep the 2 directories in sync as shown here: http://asciicasts.com/episodes/149-rails-engines
You don't need to know the files to depend on them:
file copied_directory => FileList[original_directory, original_directory + "/**/*"]
