Add new transfers as

  You can choose whether the new transfers should be added as queued and thus automatically started, or as delayed, which is better when working offline.

Show download windows

  If this is set, Caitoo will open progress windows for started transfer. You can even choose to start it iconified. This option is good if you e.g. want to watch the progress of some transfer without opening the main window. Iconified window will show progress in the task bar.

Mark partial downloads

  When this is set, Caitoo will add a special extension .part to all downloading files. Caitoo will remove the extension after the successful download. This way you know whether the file was downloaded OK or not. This option is set on by default.

Remove the file from the list after success

  Turn this option off, if you want finished transfers to stay in the list. They will have a special status icon. This is needed if you want to do some statistics about downloaded files.

Get file sizes

  When turned on, Caitoo will for all added transfers get their sizes first and display them in the list. This way you will know the size of the file before downloading it.

Expert mode

  This mode is for experienced users. For explanation see Expert mode. This mode can be toggled more easily from the toolbar.
