Where Does USB Audio Player PRO Keep Library and Settings?
UAPP reads music from your folders and USB gear, with library and DSP settings in private app storage.
Last updated
USB Audio Player PRO plays files from local folders, SD cards, USB drives, and network sources like UPnP or Samba. It never moves your music. Its own library index, playlists, and driver settings live in private internal storage.
Back up by keeping the music folders intact and noting EQ and USB driver picks. The app reads the same folders after reinstall. DAC specific tweaks like bit depth and DSD mode need a minute to reapply on new hardware.
Where USB Audio Player PRO stores this, by platform
Private app storage (library and settings)
Playlists, UPnP bookmarks, and USB driver choices. Music itself stays in Music, SD, or USB folders. Re-add network shares after reinstall.
Frequently asked questions
Do I need to move music for UAPP?
No. Point its library at the folders you already use. Keep one stable Music tree so playlists survive. USB DACs need an OTG cable and host support on the phone.
How do I migrate UAPP to a new phone?
Copy music folders over, reinstall UAPP, then re-add library folders and network sources. Redo USB driver and DSD options by hand and test with a known track.
