I have recently used iCloud for Windows (10) to download all pictures from iCloud onto my local machine. I then wanted to create a backup so I copy-pasted all (15'000) pictures onto an external hard disk.
I noticed that because of the copy-paste action, the "Date Created" has -- in hindsight obviously -- been changed from the date that the picture was taken to the date / time of the copy action.
Since the copy-action and before I noticed the change of date, I have put many hours into putting pictures in subfolders, etc. I would now like to put the original date/time back into the metadata.
My idea is to make a dirlisting of the iCloud original archive, returning filename, md5 hash, and Date Created. I then want to write a script (Powershell?) to find the matching file in my subfolders, and update the date.
A few questions:
Does this seem like the best approach?
Is there a better way to copy photo's in the future, keeping the original Date Created?
Any help into the right direction whether this is a good idea with Powershell, would be greatly appreciated.
Manually changing timestamps using PowerShell
To change the Date Created, Date Modified, and Date Accessed file properties using PowerShell, I'd recommend checking out this website here. It explains how to change the Date Created/Modified/Accessed file properties for a single file, for all files in a given folder, or even for a folder itself. For example:
For a single file:
To set the date created time for "filename.txt" to 5 December 2012 at, say, 9:57:05 PM, you'd write:
(Get-Item "C:\Users\Path_to_file\filename.txt").creationtime=$(Get-Date "05/12/2012 21:57:05")
Similarly, to set the date modified, you'd write:
(Get-Item "C:\Users\Path_to_file\filename.txt").lastwritetime=$(Get-Date "05/12/2012 21:57:05")
and for date accessed time:
(Get-Item "C:\Users\Path_to_file\filename.txt").lastaccesstime=$(Get-Date "05/12/2012 21:57:05")
You can event set properties to other properties. For example:
To set the date created equal to the date modified, you'd write:
(Get-Item "C:\Users\Path_to_file\filename.txt").creationtime=$(Get-Item "C:\Users\Path_to_file\filename.txt").lastwritetime
For all files in a folder named "Test":
Get-ChildItem -force 'C:\Users\Path_to_folder\Test\' * | ForEach-Object{$_.CreationTime = ("3 August 2019 17:00:00")}
Get-ChildItem -force 'C:\Users\Path_to_folder\Test\' * | ForEach-Object{$_.LastWriteTime = ("3 August 2019 17:10:00")}
Get-ChildItem -force 'C:\Users\Path_to_folder\Test\' * | ForEach-Object{$_.LastAccessTime = ("3 August 2019 17:10:00")}
Note that the -force parameter ensures that hidden files are also included. Also, keep in mind that if you want to change each picture's timestamps to that of its own corresponding image (i.e, if you want to intelligently automate the process), you'll need to write a script that takes care of each separate case.
Copy files while preserving timestamps (and more)
The simplest tool to use is Windows' own, built-in tool: robocopy. See Microsoft's documentation on the robocopy command here. You just run the program via the command prompt (with administrator privileges).
For your needs, suppose you have images and videos in their original form (the ones that have all the correct timestamps, etc.) in the folder "Original", located at "C:\Users\Person\Desktop\Original", and you'd like to copy all those images and videos to a folder located on your external hard drive, at "D:\Pictures\Copied". The following command would probably work best:
robocopy "C:\Users\Person\Desktop\Original" "D:\Pictures\Copied" *.* /e /copy:DAT /dcopy:DAT /mt:16 /j /xjd /xa:s /r:1 /w:0 /log:"filename_path.txt"
Each argument is explained in detail on Microsoft's documentation page for robocopy, but I'll explain them here too.
The 1st argument specifies the path to the source folder. Please note that there are no trailing backslashes! If you include a backslash at the end, robocopy won't understand the input.
The 2nd argument specifies the path to the destination folder.
The 3rd argument can actually be multiple arguments. Here, the *.* specifies the file or files to be copied. Since wildcard characters (* or ?) are supported, *.* matches all files in the source directory (i.e., everything will be copied). *.* is the default parameter, so if you want all files to be copied, you don't even need to specify this parameter. If you want to copy, say, all files that end in .jpg, you'd write *.jpg. Or, if you want to copy, say, just two files file1.jpg and file2.mp4, you'd write those out explicitly, one after each other, as such robocopy "C:\Users\Person\Desktop\Original" "D:\Pictures\Copied" file1.jpg file2.mp4 /e /copy:DAT /dcopy:DAT /mt:16 /j /xjd /xa:s /r:1 /w:0 /log:"filename_path.txt".
The 4th argument /e copies subdirectories. This option automatically includes empty directories.
/copy:DAT specifies which file properties to copy. Here, D, A, and T means that the file's Data, Attributes, and Time Stamps properties will be copied. Refer to robocopy's documentation for more details.
/dcopy:DAT same as /copy:DAT except for folders.
/mt:16 creates multi-threaded copies with 16 threads. You can specify an integer between 1 and 128.
/j copies using unbuffered I/O (recommended for large files).
/xjd excludes junction points for directories.
/xa:s excludes "System" files.
/r:1 specifies the number of retries on failed copies. Here, it's set to 1. The default value is 1,000,000 (one million retries)!
/w:0 specifies the wait time between retries, in seconds. Here, it's set to 0, so 0 seconds are spent waiting.
/log:"filename_path.txt" writes the status output to the log file.
I have looked through a lot of the questions here, and have put together about as much as I can without running into problems.
Goal - I want to check files in Folder 1 that have a date modified of > yesterday. If they exist in Folder 2, I want them deleted in Folder 2. Finally, I want to copy them over to Folder 2.
Here is what I have for the delete step.
cmd /k For %%F In ("Path_Folder_1\*.*") Do If Exist "Path_Folder_2\%%~nxF" Del "%%F" "Path_Folder_2\%%~nxF"
I figured I would do the copy step later, unless it can be combined with this step. Also, I do not know how to integrate the date check into this. I've seen "forfiles" but am not able to understand how to do the same thing with it.
Thanks so much for your help!
I have ZERO bat knowledge so thought I would ask here, if I may.
I have an image C:\Users\Dane\Pictures\Doom.jpg. I wish for this image to be copied and for it to be renamed to the exact name of 379 non-image type files which are in another folder which is G:\Doom. So I will have the same image 379 times but named to match the 379 files.
Would anyone be kind enough to write a bat file to do that? Thank you in advance.
This site is not a free code writing service; Rather give the subject an attempt and we will be happy to assist you. However, because I'm nice, I have a response for you.
This problem is pretty common and can be solved very easily using a FOR statement. In this example we will be searching a directory for every item stored inside. Each item will be added to the integer %%A. For more information do FOR /? inside a command window.
for %%a in ("Directory") DO (Action)
For copying files, we will use the copy command. Please keep note that we will be using parameter extensions to expand the %%A to have no extension using %%~na. More info here: Parameter Extensions
This script will copy & rename Doom.jpg to G:\Doom for each item in the directory.
Batch File:
for %%a in ("G:\Doom\*") do (copy "C:\Users\Dane\Pictures\Doom.jpg" "G:\Doom\%%~na.png")
Command Prompt:
for %a in ("G:\Doom\*") do (copy "C:\Users\Dane\Pictures\Doom.jpg" "G:\Doom\%~na.png")
I have read many posts covering copy and xcopy, but i am unable to get my command to work.
I aim is to create a batch file that will do the following;
Search a directory structure for a list of files 'names only' if found copy them to another directory. If not found create an error list.
The txt format of files I am looking for can be in any format however in testing i have a text file like this;
1603010853
1603020845
1603141400
1604061215
The files are .PDF or .TIF
The directory structure that I am searching is like this;
X:DEL>16>160314>1603141400.pdf
X:DEL>16>160301>1603010853.tif
I am struggling to get it to work as the list is not the full path.
for /f "tokens=*" %i in (File-list.txt) DO xcopy /S/E "c:Test\In%i" "c:out"
Thanks in advance

Alrighty, if tool doesn't matter much, I'd suggest going with the PowerShell script attached to this SuperUser post. It seems to do everything you want (including logging errors). You'd need only copypasta that into a text file, name it accordingly, and go from there.
I am a Batch-newbie, so please accept my apologies and Thanks in advance !
This "tool" is to automate the slimming down of Windows (XP) by disabling certain system driver, DLL and EXE files. Instead of outright deletion, I wish to rename-in-place, thus "removing" them from the OS, but not losing sight of where they belong (should any need to be "restored"). Renaming is accomplished by appending a new suffix to the existing filename (eg: "wdmaud.drv.group_1") The renaming suffix should be another input variable.
The target-list is approx. 1100 files long (divided into various groups/phases), so manual renaming is out of the question. Each group will be processed in a separate run of the batch file, varying the target-list input file for each execution.
Target-list is plain text file, one filename per line (no other data in the files). Number of entries per group varies. Target list will look like this:
-- example start --
netapi.dll
netcfgx.dll
netdde.exe
netevent.dll
neth.dll
netid.dll
netrap.dll
nic1394.sys
-- example end --
Filenames may be in UPPER, lower, or MiXeD case. The files may be present in more than one folder in the C:\Windows hierarchy - or may not be present at all. If a file is not found anywhere in the system, it's name should be written to a text file, one-entry-per-line.
The specific folders of interest are:
C:\WINDOWS\
C:\WINDOWS\system\
C:\WINDOWS\system32\
C:\WINDOWS\system32\dllcache
C:\WINDOWS\system32\drivers
The renaming will be done by connecting the target OS drive to another XP computer, so locked system files should not be a problem.
Any help you can offer will be greatly appreciated.
a double FOR loop may help you.. this is a very simple example, just to get you started
for /f "tokens=*" %%f in (%targetlist%) do (
for /f "tokens=*" %%d in (%dirlist%) do (
if exist "%%d\%%f" echo %%f found in %%d
)
)
