Shareaza

When I search something, Shareaza displays the the files in the search result, that I allready have in my transfers list, in blue - so that I do not download them again.
Where are these informations saved? In which files?
I often make a new system installation and installation of shareaza, and want to have the information in the new shareaza installation - of all the files I´ve already downloaded in the past or have in my transfers list!
For taking over old incomplete downloads, I just move them in the new download folder, and they are continued. But what do I have to do, to take over the information about files I already have - in the new shareaza installation?

Its not saved.

It only uses the library database to check against files that are currently within the library. So if you move to an other system and make sure all the files within the old library are also within the Shareaza library on the new system, these files are marked in blue on the new system as well.
