I'm sorry I can not remember who sent me an email asking me what the meaning of the final number in the file names of the map, poi, etc., we post.
No. 130917 means the time stamp, ie, termination year (13), month (09) and Day (17) that the file was changed by NNG.
When we download the map Toolbox by NNG of the name comes only Brazil.flb, the rest of the data we got when we rename the file with the program iGOView
