Converting the FileSystemObject's DeleteFolder Method
Definition: Deletes one or more folders.
See Delete. The only difference between Delete and DeleteFolder is that DeleteFolder allows you to delete more than one folder at once. You can use the Remove-Item cmdlet to delete multiple folders. For example, you can use wildcards to delete all the folders beginning with te from the C:\scripts folder:
Remove-Item C:\scripts\te* del C:\scripts\te*
And don’t forget, if you want to automatically delete everything without being prompted, use the -recurse parameter:
Remove-Item C:\scripts\te* -recurse
