BitComet 2.23 – Download Manager

BitComet is a BitTorrent, HTTP, FTP download management software. It is powerful, fast, very easy-to-use, and completely FREE. The advanced features allow to accelerate your downloading speed up to 5 – 10 times faster, or even more.

BitComet supports simultaneous downloads, download queue, selected downloads in torrent package, fast-resume, chatting, disk cache, speed limits, port mapping, proxy, ip-filter, etc.

Also supports 52 Languages. The app automatically finds the mirror servers for the file being downloaded.

With Bitcomet you can preview the videos only minutes after downloading has begun. You don’t need to wait dozens of hours to finish the download. At present, most of the video files on the Internet have huge sizes, some files going even as big as several Gigabytes.

And there are some torrents containing fake files which may waste lots of your time to download. With this new function, you can check the content by previewing files and deciding whether to continue the download or remove the task and its files from your computer.
