WhoHasNT allows the administrator or regular user to quickly check who is using a file/directory on an NT/2000/XP/2003 machine (server or workstation). The new version removes the need for elevated rights - Can be given to non privileged users. The easy to use windows interface is far simpler than trying to do the same job using the NET FILE command. WhoHasNT can check who has open files on an entire server, directory or single file.
