I’ve already written about unlocker, a free software which frees a file that’s locked by any application in Windows.
LockHunter is another free program, functionally similar to unlocker. LockHunter helps you analyze the program thats locking the files and hence is a perfect tool to fight malware, if any is holding on to your file.
LockHunter allows you to delete the process into recycle bin, so if you happen to delete a program/application by mistake, you can restore it from recycle bin.
It supports both 32 and 64 bit windows.
