Spring-loaded folders are a feature that allow 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 outline view.

Filter & Search

Use the search field (⌘-/) to to display only files that match the search string in the browser. Search is case insensitive and does looks for matching sequences in the filename. To search recursively, hit the 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.

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 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 (⌘-X) followed by Edit → Paste (⌘-V). To duplicate a file, use Edit → Copy (⌘-C) followed by Edit → Paste (⌘-V).

The field must loose focus (e.g. by hitting Enter 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.

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.
