Mix Wav Archiver is a Windows program that scans folders looking for what appear to be unused MixcraftTM wav files. If found, it moves the wav files to archive folders where you can delete them. It will also, at your option, restore the appearance of the Windows folder icons.
This is a utility that I created for my own personal use. I make no warranties about it. Use it at your own risk. Etc.
You can download it here.
Note that Windows Defender may block running the installation program (you can still choose to run it). That will happen until more people run the program and it earns a "reputation" with Microsoft. You can right-click on the executable, choose Properties > Digital Signatures > Iterum > Details > View Certificate to see that it is signed with a secure certificate.
You can contact me, but please understand that I do not plan to do much additional work on this.
