I am putting this on the general listing in case there are others interested whom I do not know about, but this is directed specifically to Jonathan Osuch.
 
There is a problem with map files.  They work fine for coloring, and in all ways intended.  The problem is in comparing for duplication.  Two identical maps as far as color values and sequence goes will not show as duplicate if one of the maps has been cycled and then saved. 
Would it be possible to have fractint list the map file used in the par even if the par is saved with colors?  This would provide a reference by name to the map used in the par.  Or could fractint somehow place a stop bit (sync place holder) in the map files so they could be aligned in the editor with a key entry?
The best solution would be a program which first would enter place holders within the map file so that all maps would be uniform, then run a comparison for sequence of RGB values regardless of place.  In other words, if the only difference between two, or more, map files was the linear order of the same values, it would show as a duplicate.
I wonder how many map files on people's drives are actually duplicates, with the only difference being sequence?  Just a thought.
