Search nested prefixes
Find an object without opening every folder. Results include the full path, and a local index speeds up repeat searches.
Transfer files
Upload, download or drag files to Finder. Follow progress, cancel a transfer and choose what happens when a file already exists.
Search across folders.
Search through nested folders without opening each one. Inspect a result in place, or reveal it in its original prefix. Repeat searches use the local index.
