I don't think you need to scan the drive though, through Folders in MMA you should be able to access anything. Of course that wouldn't include the convenience of browsing by artist, album or genre as you'd browse by the folder structure.

I have a related challenge and solution (almost). My library has 35k flac songs and needs a TB drive to store it. I have a Nexus 7 (2013). I got OTG cables and a USB OTG cable powered drive. I sync the 800gb of files to the TB external drive (really a laptop drive in a nice small case) and let MMA scan the drive as if it were attached. I use a custom Android rom/kernel and StickMount to allow MMA to see the drive and after 24 hours or so, MMA has scanned the files and away I go in my car. Basically, you need all OTG OS, OTG cables and a OTG device for any sizable collection of music.

I've got several MMA tickets open that are pointing to bugs in MMA when it comes to OTG attached devices. It keeps on destroying the database that takes a day to build when I gracefully shut the unit down. Not a great setup, but once this is figured out, I'll have a sweet setup in my car.

I didn't really answer your question other than to agree you can't sync NAS from MMW, which led me to a device to plug into my car stereo using all OTG devices that in turn point to what looks like a defect in MMA for huge OTG libraries.

You can't.

Hi,

A long term user of MM on PC; just bought MMA Pro for my tablet.

All of my music is stored on a NAS drive and when using MMW I specify the remote share Music folder in my library settings so that that remote folder is scanned for tracks and upates the library accordingly.

When I look at the options on MMA for library folders I can only see internal storage listed - I can't see an option to scan remote shares/UPNP locations. I don't want to copy all of my music files onto my tablet and then tell MMA to look at the tablet folder location for library purposes, I just want to specify a remote location to scan and update the library - no point filling up my tablet when the songs are sat on a NAS drive in my house.

I can access the songs using the UPnP section on MMA but that isn't the same as being able to see the tracks in a library.

How can I get this to work?

Many thanks,
J
