WinSCP Synchronize removed everything in folder despite delete option being unchecked

Hi there. I was just trying to sync my public_html folder to a folder on my PC, so I could edit my website on an program I like. But, after I synced the folders, it seems like the public_html folder was synced with the empty folder on my PC, and now my whole website is gone and I don't know how to recover it. Please help, I'm not sure what to do, and I just lost a lot of work.

I'm sorry, but there's not much we can help you with.
See https://winscp.net/eng/docs/faq_undelete

Also, I'm sure that if you uncheck the "Delete files" option, the synchronization won't delete anything. If you have a different experience and you can reproduce the problem, please post a session log file showing that.
