A free C++ BitTorrent/HTTP/FTP Download Client

BitComet Task List

The Task List is the main part of BitComet's interface. It is where your torrent jobs are displayed, along with plenty of information for each of them. There are many columns in this list, some of which are shown by default and some are invisible. You can right-click on any column header to set the visibility of each column.

Task Management Options

Use “Move Up” and “Move Down” buttons in the toolbar or Ctrl+ ↑ / ↓ / HOME / END, to change task order in the Task List. Starting with v.1.20 you can also re-arange the tasks in the Task List by clicking on the task's icon and dragging it up or down into the desired place.

Double-click a task.
- Double-clicking a HTTP/FTP task:
  - will cycle its status between “downloading” and “paused” if the task is not completed;
  - will open/run the file/folder for a completed HTTP/FTP task .
- Double-clicking a BT task will cycle its status between “running” and “paused”.

Snapshot: Snapshots from BitComet users for the download task. Hovering the mouse pointer on the icon will show the number of the total snapshots. By clicking the icon, you will be redirected to the “Snapshot” tab in the BitComet BitComet Detailed Info Pane.
Preview: Any video content task, can be previewed or played by the designated player.
Size: Size of the selected task (all files contained in this task count).

A share ratio of 1.00 is obtained when your uploaded amount is equal to your downloaded amount. BitTorrent downloading relies on each user uploading their fair share, so stopping a task before reaching a ratio above 1.00 is harmful to the community (the swarm for that task).
Health: Seed distribution on the Internet. The higher the health value the more seeds for the downloaded resource.
