i learned half-life 1's beta textures contained in hl:s vpk's.
with hope of finding interesting stuff i tried to extract them frrom vpks, i guess they are in vpk files.
i wassnt know any source modding info. so i opened valve developer wiki to learn it. i tried stuff from there but no success. (vpk.exe hl_00whatever.vpk from cmd)
i tried with source sdk 2013's vpk.exe. and tried with that common sofware i guess it was called gcfscape. but no success. in gcfscape it only shows a folder called root, but i cant access in.
1) how to open hl:s' vpk
2) are textures of hl:s stored in these vpk's?
maybe those softwaresd wont work properly in windows10, maybe this is my problem but there arent any evidence for this.
