Can I specify a "root" folder for a user?

I am wondering if there is a way how I can set a root folder for a user. For example, I have the following folder hierarchy in the Spotfire library:

/ (root)
   DNA
     UserFolder
       User_123
       User_234

Can I use specify what would be the root folder for a user to be "User_123" - the user won't be able to go up the tree using the WebPlayer but only inside their own folder

Solution

there is no capability for a feature like this.

in Spotfire 10 there is a feature called "Sites" which effectively creates unique libraries per server joined in a cluster, but I don't think it's feasible to create one server per user, and currently I understand there are some issues with clusters containing more than four servers [citation needed]. but the feature is interesting and new so, there you have it.

what I would recommend instead is to get creative with your library permissions (doc is for version 6.5 but these have not changed). in your example:

/ B+A for Everyone group (this is required)
DNA B+A or Inherit for Everyone group (otherwise nobody will be able to see it)
UserFolder B+A or Inherit
User_xxx do not Inherit, B+A+M for that specific user

the effect will be that all users can navigate up to the User_xxx level, but will only be able to see folders to which they have A permissions.
