= Changing the file permissions of downloaded files =
By default, transmission sets the file permissions of downloaded files so that only the transmission user can wrie to the downloaded files and folders. To change this, modify the settings:
1. vim /var/lib/transmission/.config/transmission-daemon/settings.json
2. Find the line: "umask": 18, and change it to "umask": 2. This will enable all users in the transmission group to also write to the file.
3. Restart transmission from the Amahi Control Panel (Settings/Servers/Transmission Server/Restart) for the changes to take effect.
