if i recall correctly, sometime back you made it so that BB could be set up to discard files of different names that were dups of files you already downloaded. if this is true, can you elaborate? does it just check for file size, or in the case of a picture, does it do more to verify?
if indeed this is a feature, is it possible to tell it to download a file of the same name as another you alrady have in your history, but is identifiably a different file?
im finding that as i download, often times people will post files as "dsc00002" or whatever, and i cant just say "dont populate history with numeric filenames" as dsc is a common prefix to many pictures, but they are entirely different in content.
