If one looks at file properties in Windows Explorer, the "Details" tab, - for many filetypes (for example, tiff or jpeg images, Office documents, etc.) there is the "Description" section with fields like "Title", "Subject", "Tags", and "Comments". Is there a way to read/write these fields from Perl or a PowerShell script?

I wrote up a blog post on how to access extended properties a while back - as in when PowerShell was still in beta and called Microsoft Command Shell (MSH). :-) I think it's still a valid approach.

  • Keith, thanks for so fast response! For the moment I did not succeeded to apply your code to modern PowerShell, I will try to dig in more :) – Vasily A Sep 28 '12 at 21:17

    Great! that example works perfectly at least to get the values, so all I needed was the .GetDetailsOf function. And what if I would like also to change values in the file - is there any way to do that? If I understand correctly, in that example fields are just copied from the file to NoteProperty members and will not be saved in the file, right? – Vasily A Sep 28 '12 at 23:33
  • is there still not a one-liner powershell/cmd statement that will allow me to access the extended attributes of a given file type? what i will be doing is spawning an instance of powershell from a nodejs script sooo – oldboy Jan 22 '20 at 06:57

PowerShell has gone through some iterations, and this can now be achieved with a native command: Get-ItemProperty

Example: Shows the current details of ntdll.dll file:

Get-ItemProperty C:\Windows\System32\ntdll.dll | format-list
