Hello, I'm using portable Tixati 1.99 64bit, and I would like to update to the latest version but it's very important that it keeps the list of torrents, configuration and folders. How should I do it safely? Thanks.

Exit Tixati. It's a good idea to make a copy of the old Tixati_portable first. Extract the new version archive and copy all content of the new Tixati_portable folder to the old one, overwriting executable files.
