I just downloaded a weapon pack and I overwritted them with my dafaults weapon.
So can anyone please upload it for me ?
Thanks in advance.

just delete models, materials, scripts and sounds folder.

If I delete the everything then how I suppose to play ?

As soon as you go to play another game, Steam will re-install all of it instantly.

Just join a server.

0.o .

Is Steam downloader faster than normal downloading speed ?

it'll take like 40 secs to download it all, its pretty small stuff.

Thanks for helping me .

... he meant,
go to computer/localdisk/programfiles/steam/steamapps/username/counterstrikesource/cstrike/
and you will see folders materials, models, sound, and scripts...delete those folder files...
and yeah if you delete some important files they will be re installed to your cs:s

your welcome.

Edit: WOAH I just relized something... its 2 years after =D
