How to restrict accessing of file

I need to restrict access to certain files in Parallel Secure Workspace based on user roles. What’s the best way to implement granular access control?

You can try below step to implement access control for files
Define Roles: Create user roles that correspond to the different access levels (e.g., Admin, Manager, Employee).
Set Permissions: Configure permissions for each role, specifying which files or folders each role can access, modify, or view.
Assign Roles to Users: Assign each user to the appropriate role based on their responsibilities.
Use File Security Settings: Implement file-specific access controls within Parallel Secure Workspace to restrict access at the file or folder level.
Audit & Review: Regularly audit user roles and permissions to ensure proper access control.
