In TeXstudio I want to associate different files with tex coloring scheme. For example, I open .stex file and the syntax is not colored. This .stex file is the same tex file, I just renamed it for some reason.
I've putted .stex extension in my ini file:
Files\Default%20File%20Filter=TeX files (*.tex *.bib *.sty *.cls *.mp
***.stex**)
But it does nothing.


.stexin the ini entry, but as you can see the markup does not work there. If you added this extension in an own line, then this is very likely the cause of the issue. On the other hand in the file to be highlighted there must some known code that can be highlighted. – Speravir Feb 8 at 1:37
