Windows 10: Batch: change target directory date after xcopy

I use this command to make a weekly back up my personal files:
Code: xcopy C:\all\* Z:\Allbak\* /C /D /E /I /W /Y[/quote] Works fine but how can I change the date attribute of the Allbak directory to the current date?

:)

 

Why can't I copy a file from a USB drive even when giving Admin permission

I have the same problem. My solution is to use Microsoft's Windows 10 xcopy command line command.

xcopy /E source_path target path

The following command line copies all directories (empty or not) from E:\AOP directory on my USB drive to the current directory.

xcopy /E E:\AOPdir .

 

How to temp set date format in a batch file?

I have a batch file for backing up my important files. I save them to my hard drive then later xcopy Mybkup to a CD. It works great if the date format is yyyy-MM-dd. I would like to set it in the batch file only. This is basically one of the lines in my
.bat file. If I change the format it messes up th file structure of my backup.

XCOPY "C:\...\Doc" "C:...\Mybkup\BKUP%DATE%\Doc\" /S /V /I /G /R /K /Y

 

XCOPY (and ROBOCOPY) don't seem to have any way to update the timestamp to the current time.

You'll have to use another utility like BulkFileChanger: Change date/time/attributes of multiple files , which can be used from the command prompt as well as the GUI.

Edit: Sorry, I think I misread the OP. Do you just want to change the modified date of the Allbak\ folder but leave the timestamps of the files the same? If so, then I don't believe BulkFileChanger will work. If you have access to the Unix "touch" command (e.g. through Cygwin or MSYS) then that's the simplest way.

 

Yes, I want to re-date the backup directory only, not the contents. Most backup programs do this with incremental backups so I hoped I could find a way.

 

If you don't mind installing something, touch.exe is part of Cygwin coreutils.





Otherwise, if you can move to PowerShell then you can also do:

(Get-Item -Path $folder).LastWriteTime = (Get-Date)





Edit: You can also call the PowerShell command from CMD like:
Code: powershell -Command "(Get-Item -Path c:\temp).LastWriteTime = (Get-Date)"[/quote]

 

Thanks for the suggestions. I found a program, Attribute Changer which inserts options to the context menu and works quite well. Not automatic but easy and quick.
