It appears that M4A (Apple Lossless Audio) files are not recognized.

right click the folder that has the M4A files.
go to file types
check on 'other'

those files should be seen now.

That works ...

It appears that only files that appear in my fopnu library folder list (displayed) are actually available to the network.

Since 'other' can refer to a whole raft of other stuff .. I would think that M4A should be added to the "AUDIO" category at some point in time.

An alternative suggestion might be to add a "fop-share" option to the file explorer "right click" to specifically select a file (or group of files) or folder to be included in the library (not copied per say - but maybe a shortcut/link).

Of course - the fopnu library display would need to display these linked files (and actual location) as well - and have the ability to override / select / deselect as well.

Just a suggestion .... so far though - fopnu looks promising !

I don't see a file types option when I right click on a folder within the fopnu library. I'm running 1.53

EDIT - Nevermind, I didn't realize that it had to be on the root shared folder.
