If you are using Windows, you probably ever encounter error message saying that a file is being used by other person or program when you are trying to delete, move or rename a file, or ejecting a USB drive. For example, if Windows Explorer is viewing the thumbnail of a video, then the video file is likely being locked by Explorer.exe. Before this, I use Unlocker to force the delete and move operation of these locked files, or when trying to eject a USB drive with opened files. Unfortunately, I can’t get Unlocker to work on Windows 7, even on the 32 bit version of Windows 7.

LockHunter is a similar tool to Unlocker. LockHunter allows you to release a file or directory that being opened by other application. LockHunter integrates itself to the right-click menu just like Unlocker. LockHunter also allows you to kill or even delete the process that is opening the file that you want to delete. This feature is quite useful especially if you know the locking process is actually a malware.

If you are looking for the alternative of Unlocker then LockHunter might be the solution for you, especially if you are running the 64 bit version of Windows. LockHunter is freeware and available for Windows 2000, XP, Vista, 2003 and 7 (32 bit and 64 bit).
