Move Files older then 31 days to another drive
I don't know if this makes much of a difference, but rather than $. it needs to be $_.
I tried this script and it works fine for me:
get-childitem -Path "E:\source" | where-object {$_.LastWriteTime -lt (get-date).AddDays(-31)} | move-item -destination "F:\target"Notice you don't need a foreach loop because the objects will be "piped" into the move-item command
