I don't think there is any big significance to the names, they can be fairly arbitrary strings.
Ah - not so! The .MDR file (not yet created by mkgmap) stores the names of subtile-files as 32-bit integers and expects the subtile files themselves to have names of the 'printf' format "I%07lX.GMP". See http://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/MDR_Subfile_Format#MDR1...
Well I don't agree. If you go to http://mapcenter2.cgpsmapper.com/ and download any of the freely available maps from there, you will see many (probably all of them) that have names that are 8 digits. It appears that all of the ones that have an installer have a mdr file. A map has a name and a number. We always make the name to be the string representation of the number, as I believe does cgpsmapper. It has never caused a problem before. ..Steve
