Moving Files

[ksigel2]

After completion of a download, I moved the receiving folder to a new location, which prevented seeding. I believe this is because Transmission does not know the new location. How do I inform Transmission of the new location?

Best option: move the file(s) using Transmission.

Code: Select all

transmission-remote -t <torrent-id or hash-code> --move <destination path>

2nd best: tell Transmission the change of location. Don't expect 100% success rate, Transmission may detect the error before you tell about the change.

Code: Select all

transmission-remote -t <torrent-id or hash-code> --find <location of files>

Of course this depends on the actual client you are using, but since you're not posting on the Mac OSX section, or the GTK section, then you must be using the daemon, or something else (and the Mac/GTK/Qt clients have the option on their context menu, and torrent menu in "Set Location...").

I would suggest that the "2nd best method" listed above really be
the 1st best method, since it doesn't actually move any files and just tells transmission where to start using the files from, in place.

I run 2 copies of transmission to provide better priority control and rpc response time, so on some regular basis I move torrents from one copy of transmission to the other -- but I don't need to change the physical location of the files..

I wrote a simple 'quick & dirty' script to do the move for me.
that assumes I am moving from my main transmission instance to
a child. It takes the name of the "torrent" file listed under the
source torrent's ".torrent" file list and uses the info found there to move it to the 2nd torrent server. If the move is successful, it removes the torrent from the first server (on failure it doesn't remove it).

It could be made more elaborate to support more children or bidirectional movement... other, less "low-level" ways of selecting the torrent (specifying the actual torrent file was the easiest way to support an unambiguous addressing since torrents can have the same name).

-I'll include it below as an example- (works for me, but
that doesn't mean it is bug free! )
