How often have you been in the middle of clearing off your desktop by deleting a bunch of unused files, only for Windows to tell you that it’s in use by another program? Except that Windows often doesn’t tell you which program is using it, so you shrug like John Travolta in that one Pulp Fiction scene. The latest addition to the immanently useful PowerToys collection can fix that problem. The File Locksmith tool is available in the latest version of the program, v0.64.0.
Using the tool is super easy. In Windows Explorer, right-click the file that’s obstinately refusing to be deleted (or in use in any other way), then click “What’s using this file?” The File Locksmith tool will then give you a list of executables that are actively accessing the file, including handy info on the process ID and user. You also get a quick “End task” button, so you don’t have to dive into the Task Manager to tell the program to buzz off.
