Use the FTP User Isolation feature page to define the user isolation mode for your FTP site. FTP user isolation is a solution for Internet service providers (ISPs) who want to offer their customers individual FTP directories for uploading content. FTP user isolation prevents users from viewing or overwriting other users' content by restricting users to their own directories.

Within their specific site, users can create, modify, or delete files and folders
