How do I set the compress bit for a file using a PS script?  I'd like to compress all files in a folder with a script like gci | compress-item (made up).

Thank you.

As a quick way to set NTFS compression (not zip), I'll use the compact.exe command in PowerShell. For example:

$cmd = "compact.exe /C /S:myfile.txt"
cmd /c $cmd

I wrote a post discussing a few zipping procedures.  If I recall correctly there is a technical differention between compacting a file (with the compact.exe utlity) and compressing it (as in when you zip files).  My post details compression and adding items to a zip file:

Nice cmille19, you could probably do something like this too:

$folder = Read-Host "Folder path?"
$task = "compact.exe /c /s:$folder"
CMD /C $task

Get-ChildItem -File -Path "C:\test" -Recurse | ? {$_.attributes -notlike "*compressed*" | foreach {compact /C $_.FullName}
