I decided to organize my music directory and was plagued by "Can't rename/move this directory as it's in use by another program".

This DLL file may be in use with another program. Deleting it can cause that program to malfunction. The uninstallation wizard of some programs shows the message mentioned above.

You can delete or can remove File Type Associations using Registry Editor in Windows 11/10. We show you how to do this the right way.
