How To: Using Cyberduck for iRODS File Transfers

Cyberduck is a free open source file transfer program for MacOS and Windows that supports several different transfer protocols (e.g., FTP, WebDAV). As of version 4.7.1, released July 7, 2015, Cyberduck supports direct data transfer into and out of iRODS. Cyberduck users can now directly upload and download files and directories from iRODS repositories using the high-throughput and parallel data transfer capabilities built into iRODS.

iRODS support in Cyberduck is due to the extraordinary efforts of the DataNet Federation Consortium (DFC) and DFC member the iPlant Collaborative, with assistance from the Cyberduck development team.

This post covers the installation and configuration of Cyberduck for use with iRODS. This is a slightly modified version of the instructions written by iPlant for use with the iPlant Data Store.

Installing and configuring Cyberduck

Install or Update Cyberduck

If Cyberduck is already installed, check if you need to update (must be version 4.7.1 or later):

  1. Click the Cyberduck menu.
  2. Click Preferences and then click Check for Updates.

To install Cyberduck for your operating system for the first time:

Go to the Cyberduck installation page at

Follow the steps for your OS:

For MacOS:

  1. Click Download (or later version than 4.7.1).

  2. Extract and move the contents of the downloaded file to your Applications folder. IMPORTANT: The file must be located in your Applications folder.

Alternatively, you can install Cyberduck for Mac OS directly through the Mac Store for a fee that supports the Cyberduck development team.

For Windows:

  1. Click Download Cyberduck-Installer-4.7.1.exe (or later version than 4.7.1, if displayed).

  2. Locate the downloaded file and double click to begin installation.

  3. Go through the install process.

Configure Cyberduck for use with iRODS

To connect Cyberduck to an iRODS repository, you must first bookmark the connection using a .cyberduckprofile Connection Profile file.

  1. Click this link to download a Connection Profile template, which contains preconfigured settings for using Cyberduck with iRODS repositories.

  2. Use a text editor to edit the contents of the Connection Profile.

At a minimum, you will need to edit the "Region" key with the iRODS Zone name and default resource that you will connect to in the format zone_name:resource_name. You may also edit the default hostname, or you may opt to configure it at runtime.

Save the updated Connection Profile.

        <string>iRODS Cyberduck Bookmark</string>

        <string>iRODS username</string>
        <key>Password Placeholder</key>
        <string>iRODS password</string>
  1. Double click the updated irods.cyberduckprofile file to open it as a Cyberduck bookmark. The profile will open so you can edit the defaults.

  2. Update the Cyberduck bookmark.

    • Update the Nickname field with an appropriate name to identify the bookmark.
    • Update the Server field with the hostname of your iRODS server.
    • Update the Port field with the port number of your iRODS server (typically 1247).
    • Update the Username field with your iRODS user name.
    • In the More Options section, update the "Transfer Files" setting, selecting "Open multiple connections".
    • Close the bookmark window.
