I have a EX Ultra and want to make sure my drive is formatted as FAT32. I used to remember looking at my NAS drives at the partition and format level. Now, i can only see it from a share height. I need this setup as a prerequisite for a NAD M50 streamer.
Internal HDD file system is EX4.
so - - the good news is you really don’t have to worry about it.
The EX2 Ultra is a fairly standard Linux based NAS (i.e. EX4 format); and using the Twonky app (if that is still a thing in OS/5); pretty much any streaming device on your network should be able to read it.
How exactly are you planning to get music from the EX2 to the streamer? Somewhere, there is an “app” reading files from the NAS and using bluetooth to get music to the streamer. Just get a DLNA app on your NAS (like Twonky) and your app should read it. Some apps can read media directly from your network without DLNA running. They don’t care about disk format. (The NAS is basically a file server in all cases)
I went through this recently. My solution was to use Media Player (WMP) on a Windows PC. . .and a USB wire to a USB DAC.
My alternative was basically use WMP to “cast” to a streamer (in this case; an amp with a streamer built in). itunes on a PC basically is the same thing; except they call it “airplay”. Airplay works the same using a tablet/phone as a music source.
