As we continue to play and download the various patches to the game, the Download directory, that is in the directory you have the game installed in, will start to fill up considerably. For example, I was really behind on the current version of QA today and then fully patched up the QA version. After it fully updated the game, I still had over 1.7Gigs of old files within the Download directory of where I have the QA version installed (from the last time I deleted everything but the latest patch): This is the number of files remaining since I last manually deleted the large number of files in here. Here is currently my Live Download Directory (from the last time I deleted everything but the latest patch): I would assume the Launcher, after patching, would have some cleanup of old files routine in it? But it does not seem to currently do this. I just wasn't sure if this is a bug or not, or something you would have to add. I just was rather concerned on how much this directly can continue to fill up and never be deleted.
