No skin folder (everyone is a steve)

Hello, i have a major problem,
Whenever i play Minecraft, everyone is a Steve or Alex. In servers and singleplayer

i see no skins, there is only Steves and Alexes. I checked my Minecraft folder, in assets, and instead of a skin folder, there was nothing.
I have tried re-installing and clearing data ect, however, there seems to be no fix.
Please get back to me, kind regards
