Already supported files should be displayed on the selection window.

Is your feature request related to a problem? Please describe. Files with the extensions .3gpp, .3ga and .WAV (in uppercase) do not appear in the file selection window, although their conversion is supported. My general workaround is to rename .3gpp and .3ga to .3gp, so that way they appear and can be converted normally. The same applies with renaming .WAV to .wav.

Describe the solution you'd like I belive it's simply a question of Ciano not seeing those files. If there was and option to select them, they would be converted normally, without the need to rename them.

Additional context Some audio recorders generate .WAV files in uppercase, and it seems that .3gpp and .3ga are very similar to .3gp.

Thank you!
