I have never changed the file extension under W10, but I have a very bad surprise!
After installing scenery of the swiss, I check the images folder, and I see that all the map_xxx_xxx files are point .ttc ! I checked the other folder 'images' and ALL the files are .ttc !
.ttc is the extension that we give to the files 'font characters' so it surprises me!
- I tried to rename 'a file' to. bmp and view it in the tool: TmfViewer but he does not want to read it.
Please, how can I fix this problem?
