In a standard FastStats system, each user gets read and write access to a private folder by default. They do not automatically get access to the public folder and its subdirectories.
Access to the public folders is granted via the Modify > Modify Access Rights option from the Users tab
It is possible to deny users access to their own private folder. You might want to do this if you want all of a user's resources to be available to other users, for example.
To configure this in FastStats:
Right-click on the relevant User or Group within the Users tab (or right-click on the Global node if you wish to configure this for all users of the system)
Choose Modify > Modify Security Capabilities
Uncheck the Inherit option and then tick the Disable user from using private folders option
Click Close
If a user is reporting that they cannot access the private folder then you need to check this setting.
The setting is stored within the UserConfig table within the webservice control database for this system.
In this example below, the user with UserId 3 in the 'Holidays2' system has got this setting defined as so they would not be able to see the Private folder within the Files tab:
