OM Octopus

OM Octopus is a simple-to-use download manager that's capable of resuming downloads after they were interrupted due to network failure.

It doesn't require installation, supports multiple threads, and comes packed with a lot of practical options for all user levels. Although it hasn't been updated for a long time, our tests have shown that it works well on newer Windows editions.

As setup is not required, you can drop the program files in any part of the disk and simply click the executable to run OM Octopus. Another option is to keep it stored on a pen drive to be able to launch it on any PC with minimum effort. Moreover, unlike most installers, it doesn't change the Windows registry settings.

At startup, OM Octopus creates an icon in the system tray area and gets minimized there. This way, it doesn't interrupt your normal PC activity while providing a quick route to creating download jobs.

The main window has a rudimentary look but it's easy to navigate. OM Octopus features a Clipboard live monitoring tool (which can be disabled) and lets you add jobs to the tasklist by editing the URl, indicating the saving directory, and specifying the threads count and number of attempts. The job doesn't automatically start afteward, but you can ask OM Octopus to do this.

Additional download settings revolve around post processing (e.g. delete files after concatenation), the proxy configuration, user authentication details for websites which require login, along with passive mode which can be enabled for FTP servers.

It's possible to edit task properties, set the status to new or interrupted, remove any job from the list, change their order, restart the thread, view URL information regarding the total size, time and restart, as well as check out thread details with the result file, remaining time, attempt number, status and progress. Log details are listed too.

The application downloaded files swiftly in our tests, without triggering the OS to hang, crash or prompt error messages. We simulated a network failure event and it managed to resume the download after the connection was re-established. CPU and RAM consumption was low.

To sum it up, OM Octopus proves to be reliable for resuming downloading jobs after they were interrupted, backed by useful configuration parameters. Too bad it hasn't been updated for a while. Nevertheless, you can give it a shot.
