Search for Files in Windows by RegEx?

Question

I want to search a folder on my computer for any file names matching "???x???.jpg".

Where the question marks can be 0-9, but I don't want it to match something like homxtop.jpg.

Is this possible?

Answer 1

Yes with powershell

PS> dir | ?{$_.name -match "^[0-9]{3}x[0-9]{3}.jpg$"}

Answer 2

chingNotCHing already supplied a solution based on PowerShell but this one could be slightly faster depending on how many folders you're looking at and it could help if you're looking into a directory structure.

Get-ChildItem -Recurse -Filter "*.jpg" | Where name -match "^[0-9]{3}x[0-9]{3}.jpg$"

What this would do is look recursively for all *.jpg starting from your current directory (which would already be a smaller set than a recursive dir) and only filter those files for the actual pattern. To just look at the current directory you would drop the -Recurse but in that case the simple dir method should be more intuitive.
