More than likely everyone knows this, but I've just figured out how to relocate the files in uTorrent that I'd moved to a different folder.
I've been trying to organise my files as from the get go I didn't set up the same folder for upload and download (when I created a new torrent I'd forget to move the file into my download folder). Anyway finally figure it out
close uTorrent
Move the file to the new location using windows explorer
open uTorrent (you'll see that the file(s) you moved have a red status
Click on the first file that has a red status
In the Detailed Window (F5) click on the Files Tab (it will show the files used in the torrent)
Right click the file(s) and click Relocate
Use the file browser to select the file in it's new location.
Click Save
Note: I relocated some of my files to a different drive and it appeared to copy them as read only. When I tried to relocate it came up with a dialogue box saying that the file was read only. Just use file browser to locate file, right click the file name select properties and uncheck 'read only' click save then try again in uTorrent to relocate the file.
Hope this helps some poor little newbie like myself!
