Remove Backups

Im quite a noobie but earning bit by bit.

My question is, I generate weekly backups but I can imagen tey will just keep building up, Now my idea is, I generate weekly backups but at the end of the month I want to remove thw backups except the last generated.

I did try look on google for answers and on here but I basicly want to know in SSH where do I go to the backup folder, And remove the backups.

Thank you.

 

I found it - Sorry I should have searched harder on here but thanks anyway.
