Issue

I want to know how to change the location of a file while continuing to seed it? E,g moving it to another partition.

Solution

The procedure is identical for most P2P clients, but the names of the menus/options may differ:

First you must pause the upload/download operations:

Stop/pause the download in Utorrent.

Move and/ or rename the file.

Select the file in UTorrent, and choose the "Files" tab.

Right click the file you just move and select "relocate".

Thanks to dolpieruse for this tip.
