Guide and tips
Why does Windows not allow you to delete some files?
Windows can prevent a file from being removed, moved or renamed when another process or application keeps the resource open. This is usual with files used by programs, system services or applications that are working in the background.
The message that a file is in use by another program does not always identify the app locking it. If closing your usual apps does not solve the problem, you may need to find the process keeping the file locked.
File Unlocker uses the Windows Restart Manager API to find processes associated with a locked file. This lets you identify which app or process is using the file before trying to unlock it.
Before unlocking a file, check which process is using it. Some locks are needed while an application is working with the file, so review the results before ending processes or making changes.
What it does
Recover locked files without guessing which program holds them
When Windows shows that a file is being used by another program, File Unlocker uses the Restart Manager API to accurately locate which process or application keeps the lock.
Once the lock is identified, the utility can release the resource or close the handle responsible so you can continue with your task.
