Unlocker是一个免费的右键扩充工具，使用者在安装后，它便能整合于鼠标右键的操作当中，当使用者发现有某个文件或目录无法删除时，只要按下鼠标右键中的“Unlocker”，那么程序马上就会显示出是哪一些程序占用了该目录或文件，接着只要按下弹出的窗口中的“Unlock”就能够为你的文件解套。
Unlocker 不同于其它解锁软件的部分在于它并非强制关闭那些占用文件的程序，而是以解除文件与程序关连性的方式来解锁，因此不会像其它解锁程序一样因为强制关闭程序而造成使用者可能的数据遗失。
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.
