G morning ! I do understand also what you mean. The main file is TrakMaps_TOPO_Quebec_3.0.1.exe (1,418600 Gb). It's in fact a compressed file and if you execute it, the following happened, you will obtain these files :
Install.exe
SetupEN.msi
SetupFR.msi
trak.cab (1,401537 Gb). Do not understand why did post a double installing file ?
Quebec001, your post remain very great. Thank You.
Have a nice day.
