Those are the default folders. You should be able to edit it so that it doesn't affect .wav files and the like
lol. yeah, editing did the trick - I simply assigned the same folder to the music files as for all the other files. However, it's not possible to delete this setting altogether - I click the delete button, then "ok", but it's still there on next mirc start. A bug?
Do note, mIRC is not a file trading program. Downloading "music" is often illegal
then why was this music files setting added to the default config of mirc anyway??!! It just causes trouble, cause it's undeletable...not to mention the fact that such a setting encourages illegal activity by its very existence
