For PowerShell commands on Windows 10, I encounter a strange behaviour.
To change a file's Date created, I use:
Get-ChildItem C:\testFile1.txt | % {$_.CreationTime = '01/11/2005 06:00:36'}
To change a folder's Date created, I use:
Get-Item C:\testFolder1 | % {$_.CreationTime = '01/11/2004 22:13:36'}
Those 2 commands work well on a regular basis on system partition C:\ or on desktop.
The story is different if the folder exists on an external USB flash drive.
(P.S. The command to change a file's timestamp still remains working on the external USB flash drive.)
Suppose I try to change the Date created of a folder (not file) on an external USB flash drive:
Get-Item U:\testFolder1 | % {$_.CreationTime = '01/11/2002 06:00:36'}
I get this error message:
Exception setting "CreationTime": "The process cannot access the file 'U:\testFolder1' because it is being used by another process." At line:1 char:31 + ... et-Item U:\testFolder1 | % {$_.CreationTime = '01/11/2002 06:00:36'} + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [], SetValueInvocationException + FullyQualifiedErrorId : ExceptionWhenSetting
Digging further, I realize that the process is Windows 10's File Explorer, which prevents me from changing the timestamp. As long as I don't open File Explorer, I can use PowerShell to change the Date created of a folder on the USB flash drive.
Is there anyway like .Dispose() to stop Windows 10's File Explorer from locking the folder without the need to close File Explorer every time?
Directory.SetCreationTime()
directly:[System.IO.Directory]::SetCreationTime('U:\testFolder1', '01/11/2002 06:00:36')
