Please note synchronization works among multiple PCs and multiple accounts.

It would be better if you create a folder for each doctor and then share the folder to the doctor from your group owner account. When you share the folders, set the access right to "Full-Access". Your group members can then logon their own account and access their files from the special shared folder: "\DriveHQ Share\YOUR_USERNAME".

In your case, since the group members upload files to their own account; you can use the web-based "Group Admin" tool  to logon as your group member and share their folder to you with "Full-Access" right. Then, logon back as your own account; you should see the shared folders in your "\DriveHQ Share\GroupMemberUserName\"

If a folder has been shared to you with Full Access right, then FileManager can automatically save modified files back to the folder. Folder Synchronization also works with shared folders.
