Unlocker是一個免費的右鍵擴充工具，使用者在安裝后，它便能整合于鼠標右鍵的操作當中，當使用者發現有某個文件或目錄無法刪除時，只要按下鼠標右鍵中的“Unlocker”，那么程序馬上就會顯示出是哪一些程序占用了該目錄或文件，接著只要按下彈出的窗口中的“Unlock”就能夠為你的文件解套。
Unlocker 不同于其它解鎖軟件的部分在于它并非強制關閉那些占用文件的程序，而是以解除文件與程序關連性的方式來解鎖，因此不會像其它解鎖程序一樣因為強制關閉程序而造成使用者可能的數據遺失。
Helps delete locked files with error messages like:
- Cannot delete file: Access is denied
- There has been a sharing violation.
- The source or destination file may be in use.
- The file is in use by another program or user.
- Make sure the disk is not full or write-protected and that the file is not currently in use.
Changes in Unlocker 1.8.5 - 07/09/2006:
