How To Use File Unlocker

In this tutorial, learn how to delete currently used, locked, undeletable, busy files with File Unlocker.

You must first specify the file or directory you wish to unlock, delete, rename, copy, or move before you can use File Unlocker. To do so, pick “Select File / Directory” and then “File” or “Directory” to specify a file or directory (folder). You can also right-click on the file or directory in Windows Explorer and choose “Unlock using File Unlocker” from the context menu, or pass it as a run-time option when running the software from the command line.

After that, you can use the “Delete,” “Move,” “Copy,” and “Rename” toolbar buttons to perform the necessary tasks, although the deletion will require a reboot to accomplish.

You must first press the “Find Locks” button to avoid the reboot.

Then File Unlocker will collect information about the processes that are locking these files or folders and display it.

You may then “Delete,” “Move,” and “Rename” without having to reboot.

In Windows Explorer, you can pick multiple files or folders, then right-click on them and choose “Unlock using File Unlocker.” Furthermore, by clicking “Enter List” and entering the paths of the files or folders in the main application, the user can pick numerous files or folders.

To unlock the file and directory handles, simply close them.
By right-clicking on the locked files and selecting “Delete Permanently,” they can be forwarded to the recycle bin or permanently erased from the system.

If necessary, you can also kill the processes that are locking files or directories and erase the processes files.

The locked file and the processes files that lock it can also be opened in Windows Explorer.

Windows Explorer Integration

File Unlocker is also part of the Windows Explorer interface. To use File Unlocker, right-click a file or folder in Windows Explorer and choose “Unlock with File Unlocker” from the menu that appears.

Selecting All Locked Files and Directories

Press the “Select” button and select “All Files and Directories” to select and display information about all files and directories that are currently locked by the system. The system then displays a list of all the files and directories that it has locked.

You should exercise caution while using this feature because you can cause havoc and irreversible damage if you delete, rename, or move files that you shouldn’t.
