Yes, replace your 50% completed torrent in the new operating system to the same folder. It works. You need to go back to the site for the torrent file.How to keep my incomplete torrent download in other operating system?
If you copy the files that it has already downloaded AND the tracker (file you clicked on to start the torrent) then put them on an external hard drive. Then when the new OS is on the system, put the tracker back on the computer anywhere and put the files in the place where bittorrent saves the files. Then click the tracker and bittorrent should to a check it will say %26quot;Checking . . . 10%%26quot; or something like that then after it's done checking it will continue to download.
