From SynologyWiki

Here is a guide on how to use sub-level folder permissions. Please note that this is not an officially supported feature of the Synology product; your experience and support may vary. This was tested using CoreFTP and a CS407 with Synology Disk Station Manager 2.0-0571. Adjust the variables as necessary

Via CoreFTP

1. Make sure FTP services is enabled
2. Login to Disk Station Manager as admin, Create a new shared folder called ftp
3. From the priviledges menu, give the folder ftp the permissions User Group, Users=RW
4. Go to user management, and create the requested users (this example will cover ftpa, ftpb, ftpc)
5. Launch CoreFTP, login as ftpa
6. Browse to the ftp folder
7. Create a folder, called ftpa
   • This will be the user subfolder
8. Go to the properties of the folder, and remove the check marks from Group and World folders (chmod =700)
9. Repeat the previous four steps for each additional user
10. You are done, the sub folders should limit the permissions via FTP or Samba protocol.

5. cd /volume1/ftp
