Hi, I already have a large number of files on my hard disk, and a very long queue of files to be downloaded. Bandwidth is precious, so how do I ensure that duplicates are not downloaded? I tried adding some of the files I know I already have and are also in the queue to my share and indexing them, expecting the queue entries to be highlighted in some way indicating duplicates, but no such luck (even after restarting the program). Am I missing something or this extremely useful feature not available? If it isn't, how do I go about accomplishing this? Can someone please help me?
