Every track file for TM2020 is a TMNF file

Hey dreadedreality,

you need to place the maps downloaded into Documents/Trackmania2020/Maps/Downloaded and then go to Local -> Play Map and open it there.

All Trackmania editions since 2003 use the Gbx file. Since you can install TMNF standalone, it binds it in Windows to the file so you can open it and play it directly. For Trackmania (2020) you need to actually place the file in the folder I described above.

Evertime i hot the dowlaod button TMNF oppens and I cant access the file i was trying to downlaod

That is because you need to save the file and not open it after download. It's a setting in your browser. Afterwards you should be able to find the file in your Downloads folder.

YOU ARE A SAINT THANK YOU SO MUCH

Have fun and welcome to Trackmania!

i have the same problem and how do i save it?

Look in your browser settings.

How do i get to my browser settings?
