You can use Windows security to control access to Project Folders 1 & 2 separately so you can grant access to files from a Timeclock station without giving full access to all files.
The timeclock folder is a feature of the Crows Nest Timeclock application.
When the user clicks on the “Files” button in the upper left hand corner they can select a Project.
Here are the steps to configure what project folder opens when the user selects a project.
Go to Settings → Options → Folders
Right click the sub folder that you want to be accessible from the timeclock and choose Set Default Location For → Timeclock Access
The Sub folder can be under Project Folder 1 or Project Folder 2
