@sylokbear-0 If you uploaded a folder, your torrent client will download a folder. This means that you need to set the download location one level BELLOW the uploaded torrent folder.
For instance, if the folder is "C:\Downloads\Torrent Folder" you need to set the download location to "C:\Downloads"
If you set your download to "C:\Downloads\Torrent Folder" then an additional folder will be created inside of it, and the files will not be found.
Remove the torrent from your software and add it again, set the location properly this time and it will start seeding right after checking the files.
