Connection Profiles

Connection profiles (.cyberduckprofile) are plugins describing specific connection settings for a hosting provider to make it easier to setup a connection to your provider. A connection profile is installed and adds a provider option in the protocol selection drop down menu in the Connection and Bookmark panels. No need to enter the connection details manually other than credentials.

Preferences → Profiles

Select connection protocols in Preferences → Profiles to be installed in addition to the default protocols listed below. Either scroll through the list or use the search function to look for a specific profile. The connection profile will be installed after enabling the corresponding checkbox. To disable a connection profile simply uncheck the checkbox. The profile will be disabled after closing the application.



You cannot disable default protocols or connection profiles currently in use in any bookmark.

Retaining the modification date for files uploaded is not supported for all protocols.
