Preferred Apps for File Transfer

Wherever possible we strongly recommend that you use's native apps as opposed to third party apps such as FTP apps.

In order to support the fastest possible speeds, we have built many optimizations into the apps that we provide.

These optimizations include things like automatically tuned parallelism, intelligent routing around corporate firewalls, and more. We have also added much of this technology into our SDKs.

Here are our apps ranked by speed: Command Line App (CLI)

Our fastest app is command-line only, but supports a wide variety of sync scenarios and scriptability. The CLI supports our most advanced acceleration technology and always wins hands down in speed tests. Download, install, and start benefiting from our fastest app. Visit our Command Line App (CLI) documentation for more details. Desktop App for Windows/Mac

This app is integrated with the Windows Explorer and MacOS Finder and provides highly tuned upload and download performance. This app is also where is putting many of its development efforts around speed, so investing in this app will be the best way to benefit from future improvements. Visit our Desktop App for Windows/Mac documentation for more details. Mobile App for iOS/Android

If you are on a mobile device, leverage our mobile apps for iOS and Android for fast parallel file transfers. Visit our Mobile App for iOS/Android for more details. SDKs for Developers

Our SDKs include the same optimization technology as our CLI app for optimum speed. Visit our Developer Portal for more details.


Cyberduck is a third party app that offers native integration in a client that works like a typical FTP client. If our Desktop App is unable to work for you due to your configuration, we recommend Cyberduck. You can download Cyberduck from the Cyberduck website.

Once inside Cyberduck, do not choose FTP or SFTP as the connection type. There is a option when you go to add a new server.
