Short answer
No. Permissions are set at the Project level, not for individual folders within a Project.
Full explanation
AskTuring’s permission system applies to the entire Project. When you give a user access to a Project, they inherit the same level of permissions for all folders and files inside it. This means:
You cannot restrict access to only certain folders within the same Project.
If you need different permission levels for different sets of documents, you will need to create separate Projects and assign permissions accordingly.
Tips
Plan your Project structure with permissions in mind before uploading large numbers of files.
Use separate Projects for sensitive material that only certain users should access.
