Sure its the smart thing to do. I absolutely agree on making sure you have backups of your files. However what if the software decided to delete some non musical files that you didn't think to back up?
Some files have similiar file format names. mp4/mpeg4/mpeg-2/mp3
Some of those are music file formats, some are video and some are both.


Should not be deleting anything without permission. At the very least this should be an option on the software to ignore certain file formants and from certain folders.
