It would be nice if OPFS (Origin Private File System) allowed reading/writing to an actual SQLite file on the users disk.

At the moment, as I understand it, the OPFS virtual disk is completely isolated from the users disk.

This means you cannot just lightly query a 1GB file without first copying the 1GB from the users filesystem to the OPFS.

Any writes mean you must then copy the 1GB SQLite db file from OPFS to the users local filesystem too.

Is this correct?
