"sfx" file has flown

[razdvatri]

Hello, please give me a standard file "sfx".
I just lost this file and my engine sound disappeared

From the Steam Library section, right-click on the game and select Properties from the menu. Select the Local files tab and click the Verify integrity of game files... button.
Steam will verify the game's files and download any missing
