On Linux!

Whenever you want to move a torrents data to a different location, the dialogue asking for the destination takes a long time showing the file system tree if some disks are currently sleeping and it wakes up these disks to be able to show the full file system tree.

It would be dearly appreciated if this behaviour could be avoided and disks only be spun up when you navigate into these in the tree.

That dialog is standard KDE stuff, we only use it, if you want changes to that report a wish at http://bugs.kde.org for kdelibs
