I recently moved a lot of my torrent files to a new hard drive which has a different letter; otherwise the paths are the same.

How can I batch update the locations of all the torrents that moved? Selecting the new location separately for each torrent will take forever...

Well, I have manually updated the location of all of the files. Would be nice if there was a batch location update feature.

Or perhaps more generally useful, since it may be that nobody else needs that, a faster way to select directories. It would be nice if the directory selection dialog would jump to or filter candidates based on a substring if you type, like select boxes usually do.

Better way is to move data with Tixati, Right click transfer > Local Files > Location > Move. You can do it on multiple transfers at once. This way you can keep seeding while relocating data.
