Unlocker is a free tool to unlock the file from being used by another program. I find it really a good tool.
What is Unlocker?
Do you had such kind of error?
it can be like this as well
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.
Unloacker is the solution for that
How to use unlocker?
Simply right click the folder or file and select Unlocker
