A Microsoft Powershell command for the brave / foolish-of-heart!

This - I hope:

1. looks through all the sub-folders of your present working directory:
2. finds all files that have the extension “.rdata”
3. that haven’t been updated since 2024-01-01
4. and (permanently) deletes them

Get-ChildItem -Recurse -Include *.rdata | Where-Object {$_.LastWriteTime -lt '2024-01-01'} | Remove-Item -Force

Of course you can change the file extensions and dates of relevance to your own needs.

This appears to work for me on the Microsoft Powershell that’s pre-installed with Windows 10. Powershell itself though is available for several other operating systems. Definitely no guarantees from me though that it’s correct and/or won’t destroy your computer.
