Where Does Daijisho Store Library and Settings on Android?
Daijisho keeps its scanned library and artwork in private app storage, with ROMs staying in your folders.
Last updated
Daijisho is a launcher, not an emulator. ROMs stay in the folders you chose during setup. The scanned index, scraped box art, and platform mappings live in private app storage under scoped rules.
That split guides backup. ROM folders copy normally. Library polish (art, custom collections, player mappings) needs the in-app backup and sync features. Reinstalls without a backup rescan from zero, which takes a while on big libraries.

Private app storage (library and artwork)
Index, metadata, and cached art. Exact subpaths vary between Play and APK builds. Use Daijisho backup and sync rather than file managers.
Frequently asked questions
Do I need to move ROMs for Daijisho?
No. Leave ROMs where your emulators already read them and point Daijisho platforms at those folders. Moving ROMs breaks emulator save paths too, so keep them stable.
How do I migrate Daijisho to a new handheld?
Copy ROM folders identically, reinstall emulators first, then restore Daijisho backup and resync platforms. Remap players only where package names changed on the new device.
