Cyberduck Help / Howto / Browser

List and Outline View

Select View → as List (⌘1) or View → as Outline (⌘2) for expandable folders. You can expand and collapse folders using the right and left arrow keys in the outline view.
Navigate into a folder with a double-click (macOS ⌘↓ , Windows Ctrl+Down) or one level up by using the ▲ button next to the path-field (macOS ⌘↑ , Windows Ctrl+Up).


On macOS, enable tabs by default when choosing File → New Browser (⌘N) by selecting in System Preferences the checkbox Dock → Prefer tabs when opening documents: Always. New browser windows and the transfer window will then be displayed in a single window frame with a tab bar. You can merge windows with View → Show Tab Bar and Window → Merge all Windows.

Spring-loaded folders

Spring-loaded folders are a feature that allows you to move a file or even another folder, into a folder deeply nested within several other folders using drag and drop. To enable, choose Preferences → Browser → Use spring-loaded folders when dragging files and adjust the delay for the folder to expand when hovering over with the mouse. Note that spring-loaded folders are only supported in the outline view.

Filter & Search

Use the search field (macOS ⌘/ , Windows Ctrl+F) to display only files that match the search string in the browser. Search is case insensitive and does look for matching sequences in the filename. To search recursively, hit the return key (⏎). The following protocols have a server-side index that is used to give fast results without recursively descending into folders.


You can sort the file listing by clicking the table column header. Choose View → Column to add more headers such as Kind to allow sorting by file type including folders appearing first in the list.

Local disk file browser

Choose your computer name from the protocol selection popup button in the New Connection window.

Alternatively, you can use drag and drop or Menu File → Upload (macOS ⌥↑ , Windows Alt+Up). You can also copy (macOS ⌘C , Windows Ctrl+C) files in your file browser and paste them into Cyberduck using Menu Edit → Paste (macOS ⌘V , Windows Ctrl+V) afterward.

See other upload methods.

Working with files and folders


You can edit any file on the server using your preferred application. See Edit Files.

Create new folder or file

Use File → New Folder... (macOS ⇧⌘N , Windows Ctrl+Shift+N) or File → New File... (macOS ⌘F , Windows Ctrl+Shift+F) to create a new folder or file on the server.

Move or duplicate files and folders

You can move files in the browser as you would in the using drag and drop. Use the modifier key on macOS or the "Ctrl" key on Windows to duplicate files. If connected to the same server, you can also move files between different browser windows.

The following protocols allow duplicating files on the server without downloading and uploading but copying in place:

To move a file, use Edit → Cut (macOS ⌘X , Windows Ctrl+X) followed by Edit → Paste (macOS ⌘V , Windows Ctrl+V). To duplicate a file, use Edit → Copy (macOS ⌘C , Windows Ctrl+C) followed by Edit → Paste (macOS ⌘V , Windows Ctrl+V).

Copy files and folders to different server

You can copy files between arbitrary servers when connected to with two open browser windows. Drag files from one browser to the other to transfer files between servers.

Copy files between servers

Rename a file or folder

Select the file in the browser and press the Return key. Type the new name and press Return again to exit the editing mode. You can also rename files by choosing File → Info (macOS ⌘I , Windows Alt+Return) or press the Get Info toolbar button. Simply enter the new name in the very top field. The field must lose focus (e.g. by hitting Return or Tab) to commit the filename change.

Choose File → New Symbolic Link... to create a symbolic link. This is supported on UNIX systems with a SFTP connection and some FTP with SITE SYMLINK extension.

Info Window

Select the file in the browser and choose File → Info ( macOS ⌘I , Windows Alt+Return) to display detailed attributes of a file in a tool window. It allows to change permissions, manage content distributions for cloud services, and settings specific to the Amazon S3 service.


macOS only
You can toggle Quick Look in a Cyberduck browser for any file using Space Bar. A preview is rendered depending on a Quick Look Plugin available on your system for the given file type. Many file types like different image formats can be previewed with the bundled plugins in OS X and HTML is even rendered in the Quick Look preview panel.

Open or Copy HTTP URL

See bookmark Web URL configuration for HTTP URLs. You can select multiple files to open/copy all URLs.

  • Open Web URL. The Web URL can be found in the File → Open URL menu and as an optional toolbar item in the browser window. Use View → Customize Toolbar... to add the Open in Browser button to your default browser toolbar.
  • Copy Web URL. The Web URL can be found in the Edit → Copy URL menu.
