Hello, and thank you in advance to anyone who can help me with my strange problem. I have a mac with a fairly limited hard drive - I previously had about 28 GB free - so I often download torrents to my external hard drive. In this case, it was quite a large file, about 50 GB, going to the external. At some point I started up the application when the external was not attached, and the following problem happened. The application tried to automatically download the 50 GB file to my local hard disk, then told me there wasn't enough space. Fine. But in scanning the hard drive for the space - i.e. creating a "dummy file" like torrent downloads do, with the full size of what will be the completed file - my hard disk was showing as completely full. By deleting various things I managed to get this back up to 2-3 GB or so, but obviously nowhere near the 28 I had before. Now, there is absolutely no file on my computer, visible or invisible, bearing any reference to the name of the torrent I was downloading. So there is nothing for me to delete to get all that space back. What can I do? I should note that I made a dumb mistake - I deleted the original torrent file thinking that might get rid of the problem - so I can't access anything through the torrent anymore. I just have this ghost eating up a huge swath of my hard disk. Any advice?
