Function Move {
#Moves all files older than 31 days old from the Source folder to the Target
Get-Childitem -Path \"E:\\source\" | Where-Object { $_.LastWriteTime -l
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
