"lockable" is the word used by Garmin (look at BaseCamp for example).Originally Posted by osiris4isis
According to Garmin, a file is lockable when the map levels section is encrypted (and other bytes in TRE subfiles are changed).
When a file is lockable the flag at TRE+0x0D is set: this flag just indicates that the file is lockable. Of course, if you change the flag, the file remains lockable...
????? I don't understand how you lock a file... it is not easy. You must use a 32 bits key and the correct algorithmThe original file wasn't locked? I can lock it (at any time) if I put in encrypted map levels and set flag, right?
