Can I delete Android OBB folder?

The answer is no. The only time the OBB file gets deleted is when the user uninstalls the app. Or when the app deletes the file itself. On a side note, which I happened to find out only later, if you delete or rename your OBB file, it gets re-downloaded every time you release an app update.

Where do OBB files go Android?

OBB file has been downloaded in Zip file. Unzip it or extract the data file. Copy the folder stored with “DATA” and move it to, External storage (SD Card) → Android → Data. If it’s an OBB file, move it to, External storage (SD Card) → Android → OBB.
