Unless there is a backup somewhere . . . . Once data has been deleted, it is gone.

Some might be able to recover deleted files via the computer's recycle/trash bin. Or by using restore points.

Why did you delete the data? Is there a problem?

Hi thanks for the answer.

Whats restore points? Can't see anything i my trash in

I was having issues with a site and slow computer, so thought if clearing cookies, cache and all that, it help. But, just didn't think of all the other factors, just a thoughtfulness decision really, and mainly as it affects a buy/sell page I use which is in 2 steps, now all my started ones step 1 are gone, so gotta start and pay again. Was hoping it be a solution to recover and not having to do it again.

A restore point, in Mac's I think it's called Time Machine, is a way to turn back the system to a previous configuration. This can bring back files you had before. Contact Mac support.
