I have about 1,500 folders where the last 4 digits represent a year. I need to add parenthesis around the year while preserving the rest of the name. The folder names vary in length from about 4 characters to over 20. Some of the folder names contain numbers other than the date.

I found a way to put a parenthesis at the end of the folder name. As well as a way to add a parenthesis at a certain place from the beginning of the name. But cannot seem to find a way to count backward from the end of the name.

Get-ChildItem -Directory | Rename-Item -NewName {$_.Name -replace '^' ,")"}

Get-ChildItem -Directory | Where-Object {$_.Extension -match '^\.(\d{4})$'} |
    Rename-Item -Newname {$_.Name -replace $_.Extension,(".({0})" -f $Matches[1])} -WhatIf
