Hi Bitshare:

I now know why BDT uploads duplicates!!

I just tested uploading 4 files. BDT only works with 2 simultaneous upload each time. Fair enough, so I upload 2 files at a time:

1) Uploading FILE1 and FILE2 at the same time
2) I stopped the transfer before they complete....or when FILE1 and FILE2 err and aborted for whatever reason (most of the time they are "Unable to write" errors)
3) When you click on Start again, BDT will skip FILE1 and FILE2 and will go on to uploading FILE3 and FILE4.
4) When FILE3 and FILE4 completes, BDT went back to the start of the queue and re-upload FILE1 and FILE2. That's good...for now.
5) But the problem now is BDT will re-upload FILE3 and FILE4 again when FILE1 and FILE2 completes as if going on an endless loop, and subsequently reuploads FILE1 and FILE2 again.
6) When it runs out of files to upload, BDT crashes with a "Bitshare Desktop Tool has stopped working" error dialog.

That's how I sometimes find files that are duplicated with different link codes.

If you stopped a transfer, make sure to remove everything from the queue and re-add them back in. Otherwise, it will upload everything twice! I normally restart BDT just in case....
