How to clear the cache?

[GearSS0nic384]

When I start the game all starts well but after "team fortress 2 classic" closes the game suddenly and says try clearing the cache but not how to do it, can someone tell me please?

Hi @GearSS0nic384, I'm confused to what you are asking. Could you perhaps record a video of the problem?

right click on Source SDK 2013 Multiplayer Base beta_test, click on properties, go to the Local Files tab, and verify the integrity of the tool cache.
