Seed an existing file

From AzureusWiki

If you have downloaded something but removed it from Azureus and wish to seed it, follow these steps

Please Note: you must have the original .torrent file.

1. Go to File > Open > Torrent File...
2. Select the .torrent file for the data from it's location on your hard drive using the Add Files button

   

3. Select Seeding as the Add mode for the torrent. (For downloads, the "normal" mode is Queued)
4. Select the location where the data file to be seeded is stored
5. Wait for Azureus to finish checking the data file. When it does, the torrent will move automatically from the download window into the seeding window

If the torrent does not move into the seeding window on its own: Right-click on newly created entry in the download window of the My Torrents view. Select Force Re-check. The value in the 'Done' column will count from 0% to 100%. Upon reaching 100%, the file will be moved to the seeding list on the bottom of the My Torrents tab.

Note: A more thorough explanation of the process can be found at the article How do you resume.

If you do not have the original .torrent file but the original data, try this

1. Download the same .torrent file again
2. Azureus will check it out
3. Azureus will move it to the seeding list (the process is very quick)

Also, learn about the (almost) unlimited Ignore Rules options you could (and should) use to automatically seed and then stop your torrents and also to best support rare torrents.
