Problem is : I got a back-up of my computer about half year ago, with Tixati installed.
Since then I did quite a few DL's.
But now my operating system makes problems (Win 7 - 64),
so I might be forced to start with the backup again and go on from there.
I have saved my DL's on an external drive.
When I start from my Backup, I don't know, how to get the DL Data back.
There must be somewhere a data-file, that read like DL-Name,TotalSize,HaveSize,Hash.
If I don't find that file, I still have my DL's on the external drive, but I can't seed no more!
So - anybody knows the name of that Tixati data file ? Thanks !
Or maybe I'm totally wrong, how Tixati knows, what is its file.
Can anybody clear this issue ?

Tixati has Import/Export function (in Settings). It works OK but has one downside: doesn't save boundary pieces for partial downloads. You can copy whole Tixati settings folder, install fresh Tixati and paste old settings (including boundary pieces). Tixati data files are located in %appdata%\Tixati folder.
