  1. To create new folders, click the File menu.
  2. Select New Folder.
  3. Enter the name of your new folder.


Viewing Files and Contents

Cyberduck unfortunately doesn’t allow you to view files without downloading them to your local computer.

  1. Select a file you would like to view. Double click the file to download. A message will appear saying download is complete.
  2. Double-click on the file downloaded. There will be 2 copies of the file; one in AFS and another one in the download window.  Note If you have done this twice, it will open up the Overwrite window. Select Continue.

    • macOS - click the file and select move to Trash.


Downloading Files and Contents

  1. Cyberduck will allow you to transfer a single file or an entire folder. The Download Folder specifies the folder on your computer that you would like to automatically download.
  2. Select the file or folder you would like to download and drag the contents to your desktop or a location of your choice.  Note You can stop downloading of files by clicking stop above the transfer tab.
  3. Once downloaded you can open the files or folders.


Uploading Files

  1. Select Upload from the taskbar in Cyberduck.
  2. From the Open window, select the file that you want to upload.
  3. Click Choose.

Please note: You also have the option to drag and drop files into the SFTP window from your computer. It will open the Transfer window with Cyberduck. The file will be highlighted in the SFTP window.



Moving Files

The Browser window is the main part of the application window in Cyberduck. The folders and files that you see in the Browser window can be thought of as a Finder (Mac) or Explorer (PC) window for your FTP server. Therefore, transferring files with Cyberduck simply involves dragging files from one window to another. Select File to move.


Transferring Files

The Transfers window allows you to track the status of file transfers. The Transfer window is located on the taskbar of Cyberduck. The Transfers window will display:

  • The direction of the transfer (noted with an arrow pointing up or down)
  • The transferred file name
  • The status of the transfer (Transferring, Complete, Incomplete)
  • The size of the file
  • Deleting Files
  • Select File or Folder to delete.
  • Right Click on the file or folder.
  • Select Delete or press delete on your computer.


Syncing a locally downloaded folder to your AFS version of that folder

  1. Download the folder to your local computer that you would like to make changes in, and then use that local copy to keep your AFS version up to date.
  2. Make any changes in the folder that you would like to make and save them locally in that folder you downloaded.  (You do not need to have Cyberduck open and active for this step once the folder has been downloaded locally.)
  3. If you do not have Cyberduck open and connected, open up Cyberduck and connect to the server.
  4. From the File… menu, click on Synchronize… which will open up a file browser in the Cyberduck window, for you to navigate to the folder on your local computer to synchronize.  Highlight the folder and click Choose.
  5. A Transfers window will open, and allow you to choose in a dropdown how you would like to keep the files up to date for this transfer.  The options are:
    • Download - Download changed and missing files
    • Upload - Upload changed and missing files
    • Mirror - Download and upload, which keeps the folders in sync in both places.  This can be a good choice if you plan to use this feature on multiple computers with that particular folder.
  6. Once you've made your selection in the dropdown whether to Download, Upload, or Mirror, click Continue.
  7. The Transfers window will show the progress and let you know when the Sync is complete.
