Users are unable to rename folders they created under shared data. They are also unable to save programs and such to the shared data folder locations. I looked at the SAS Folders File path and that is indicated to the Content Server which does not come up as a file path option in Enterprise Guide.
Is this a custom installation or on SAS Academics on Demand?
If it's your University installation you'll need to talk to your administrators. Otherwise, if it's OnDemand, I don't believe there's a shared space for students to share code. I put a suggestion for that to be added in the SAS Ballotware last week.
