MDownloader is a simple download manager that makes it easier to access files on file hosting services.
If you've found a lengthy list of Rapidshare links, for instance, there's no need to download them individually any more. Just copy them to the clipboard, and MDownloader will pick them up automatically.
There's no need to visit the hosting service yourself. You're not forced to hanging around waiting while the timer ticks down, and generally you don't even have to complete the captcha - a built-in OCR engine will usually complete it for you. All you have to do is click a button, then, and leave the program to grab your files.
If your download is interrupted, for some reason, then MDownloader can resume it later (as long as the hosting service supports it in anonymous mode). And when it's finished, you can use the program's RSS monitoring, FilesTube and Release Database search features to find more interesting files.
MDownloader currently works with Bitroad.net, DepositFiles.com, EasyShare.com, FileFactory.com, Hotfile.com, Klurk.com (aggregate), Letitbit.net, Load.to, MegaUpload.com, Rapidshare.com, SendSpace.com, uGotFile.com, Uploading.com and zShare.net.
