Restore Transmission previous (OS 3) session

Hello to everyone,

I recently upgraded my My CLOUD EX 2 ULTRA to OS 5 and reinstalled Transmission.

Since I was using Transmission remote GUI, I had changed default folders. Now my new Transmission app isn’t able to “restore” my previous state. Of course I have both complete and incomplete files on the drive, but I won’t be able to know which torrents I had added and, maybe, had not yet started downloading, nor to continue incomplete downloads. So my Transmission is now starting again from scratch.

Is there sime file somewhere were all the information is written?
