Hi Jon,

Kentico CMS does not have any built-in modules designed for this purpose. The closest out-of-the-box feature to FTP server I can think of is Contribution list web part. However, it will be necessary to make quite extensive customizations to make it look like a real FTP server.

Another approach could be creating folders in content tree for every user and giving access to this folder only for him and denying it for everyone else. This could be set by administrator through Properties -> Security tab. However, it is still just something to make Kentico CMS look like an FTP server.

Although there are some ways using which you could set up a working FTP server like the ones I mentioned, a well-rounded server would require developing a custom module.

Best regards,
Filip Ligac
