Excellent! I appreciate that. Sending via gmail shortly...
Ditto on this problem, were Fuelio can't find the data backed-up.

I moved from an original Galaxy S to an S4, and I took the SD card across too. I have several files in my directory structures:

\Phone\Fuelio (on new S4) is totally empty.

\Card\Fuelio\backup-db (sd card) has
fuelio2.db
fuelio5.db(biggest of the 3 databases)
fuelio.db

Copying the contents of \Card\Fuelio\backup-db to \Phone\Fuelio\backup-db didn't make it find it either.

Can you specifically tell me which file goes where for it to find the backup? Is the fuelio5.db the one it will restore from (all have same date)?

Thanks!
