Hi,
What haylau is saying is right because prestashop folder is important. You have uploaded product images,custom modules installed,customization in prestashop and many more changes are written in files. So database and files both are important.
Check with godaddy when someone delete folder or files it goes in thrash (Linux) or recycle bin (windows) folder.Is it possible to recover from there?
