how to delete specific folder and all of its old verions on windows server 2008

on windows server we have snapshots taken twice daily.

now there is a folder to be deleted but can't seem to get rid of all the old versions

for example the backup for a specific version \\localhost\C$\@GMT-2013.07.31-18.00.36 is the top level folder and is write protected, how do go about unprotect and delete a specific subfolder?

actuallly I get media is protected if I try delete iva any method, icacls to change access  gives access error

is there  a script I can write to go clean up all versions of a specific subfolder such as folder2Begone?
