Used XS++ on my W810i using america_2. After i got into file explorer and found languages in tpa/preset/custom/language/. I was wondering does anyone know a way to delete the other languages? I just want english.

this is whats in there:
allowed_language.txt
en.lng
es.t9
lng.dat
lng.lst
pb.lng
pt.t9
wdb.t9
xl.lng

If I can't just delete them, is there a simple way to just insert only english without a lot of trouble?

Just delete them, no problem.

ok thx, but which ones do i keep?
i assume en.lng is a keeper
but what of the others

Delete the others, AFAIK WDB.t9 is YOUR words that you added to the t9 dic.
