Where Are Android OBB Game Files Stored?
Android/obb per package expansion files for large games plus the matching Android/data folders.
Last updated
Large Android games split APK code from bulk assets in OBB expansion files under Android, then obb, in per package folders. Main and patch OBBs pair per game version.
Deleting OBBs forces multi gigabyte re downloads. Sideloaded installs need the OBB in the exact package folder or the game asks to download again.
Where Android stores this, by platform
/storage/emulated/0/Android/obb/[package]
Visible as Internal storage/Android/obb. App private data sits separately under Android/data with the same package name.
Frequently asked questions
Game says downloading extra data every launch. Why?
The OBB is missing, version mismatched, or on adopted storage the game rejects. Place the right main plus patch pair in the package folder.
Can I move OBBs to the SD card?
Only if the game supports it; most check internal storage only. Moving by hand breaks signature checks on launch.
