This is an oldie but a goodie for anyone wanting to use their own *.TTF Font files to replace the stock WoW UI Font. I like using the Google Inter font (medium weight).
Add the following to a text file then change the file extension from *.txt to *.bat:
@echo off
REM Make a folder called “Fonts” in your WoW folder, i.e. C:/World of Warcraft/Fonts/
REM Put this .bat in there
REM Double click the .bat to run it, and drag n drop a font into the window and hit enter
REM Done!
cd
set /p newfont=“Drag n drop a .ttf here: …”
copy %newfont% “FRIZQT__.ttf”
copy %newfont% “ARIALN.ttf”
copy %newfont% “MORPHEUS.ttf”
copy %newfont% “FRIENDS.ttf”
copy %newfont% “skurri.ttf”
pause
