There are a number of reasons you might want to access your save game - maybe you need to move it between devices or maybe we've asked you to send it to us to assist in reviewing a possible bug.
On some devices, it may be possible to access your saves by plugging into a PC, for others you will have to use a file explorer app on your device (Androzip and ES File Explorer are two good free examples). In either case, you will have to navigate to the folder ‘Android/data/com.sigames.fmh2016/files/com.sigames.fmh2016/save_games’
The .dat files are your save games, and there can be up to 6 of them. The Manual Saves are named fm_save1.dat through to fm_save4.dat with the name reflecting the save slot used (1 = top slot, 4 = bottom slot). hidden.dat and hidden2.dat are the current rolling Automatic Save files on the device (saving alternates between the two). Please see the screenshots below for more information.
