Hi Megan,
Here's a slight variation on Shay's script that adds support for renaming
hidden files as well, plus it detects if some files already have the prefix
you want and skips them.
Get-ChildItem C:\Scripts -Force | Where-Object {(-not $_.PSIsContainer) -and
($_.name -notmatch "^$($_.directory
..name)_")} | Rename-Item -NewName {$_.directory.name + '_' +
$_.name} -Whatif
Be careful with the line wrap. This is a one-liner, so make sure you put it
on one line when you paste it into PowerShell.
This will allow you to run the script on the same folder over time as you
add files to it without worrying about it re-prefixing all of your files
that already have the prefix.
