Microsoft’s PowerToys for Windows 11 and Windows 10 has been updated with a new feature called ‘File LockSmith’. So what exactly is File Locksmith? In technical terms, it is a Windows shell extension that lets you check which files are in use and by which processes.
Up until today, it was not possible to find out which particular process is using the file on Windows. While Task Manager lets you eliminate processes, it cannot tell you what’s using your files or preventing file transfer. In fact, File Explorer will block your attempts to delete a file or folder in use by a process or app.
I lost count of how many times Windows would just stubbornly refuse to delete a file or directory because it was in use by some process, while not telling me which damn process we’re dealing with. Isn’t it absolutely bananas that it’s 2022 and you have to download some shell extension to get this basic functionality?
