difference = Dir.entries(@download_directory) - @current_downloads

If you subtract one array from another you get the difference. In this 
case, the difference is the most recent file.

"BR.bmp.part" is the result of a temporary file being created during the 
download, this is one of the reasons I said the download waiting method 
needs a bit of rewriting. It should continue to look until there is only 
one file difference, but a "part" file might mess that up because the 
difference is then two files. You'd just have to adapt the code to suit 
that scenario.
It isn't something I've had to deal with before because all the file 
downloads I've done have been tiny.
