Deleting a file from the remote server that hosts a Contribute site works much like deleting a file from the server for any Dreamweaver site. However, when you delete a file from a Contribute site, Dreamweaver asks whether to delete all older versions of the file. If you choose to keep the older versions, Dreamweaver saves a copy of the current version in the _baks folder so you can restore it later.
Renaming a remote file or moving it from one folder to another in a Contribute site works the same way it works in any Dreamweaver site. In a Contribute site, Dreamweaver also renames or moves the associated previous versions of the file that are saved in the _baks folder.
