How can I tell which maptile file goes with what?

open the maptile .img files in sendmap20 (screenshot)
open the maptile .img files in img2gps (screenshot)
save the mapset in Mapsource, export as .gdb, and import into img2gps using the List | Load box seen in the bottom center of the img2gps screenshot.
open the overall map .img file and use the pointer tool to hover over the area you want to identify (screenshot). In this example the St. Peterburg, FL area is mapped in 00144543.img
in some mapsets you can strings the .img files.
