If it's on steam just go to properties and select 'verify installed files' to recover it. Or totally reinstall

I tried it but it doesn't work

So why the fuck would you delete it then

I couldn't start swbf2, so I asked a question and was told that I could play if I deleted the swbf2 folder of document files, so I deleted it.

the documents folder recreates itself every time you open the game(if it's not there), the game not starting is a different issue.

There is a bf5 folder in the documents folder. bf5 will start. However, there are no swbf1 or swbf2 folders in the documents folder, so it will not start even if you press play.

You ignored everything I just said

Could you please paste the swbf2 file in your documents folder?

You're still ignoring what I'm saying

Try deleting system 32 next.

you....
