Hello swastikaha. to Windows 7 Forums,

Check the ACL of the parent folder and make sure that permissions are set to replace permissions on child objects. Also make sure that you are the owner of the folder and have full control permissions. Also make sure NETWORK is added to the ACL of the parent folder and give whichever permissions you wish.

You can also use this tool;
LockHunter


Hope this helps
