Developer David Kocher has updated Cyberduck (http://cyberduck.ch/) — an open source FTP, SFTP, WebDAV, Cloud Files andAmazon S3 browser — to version 3.5. The upgrade featuressupport to store and retrieve documents from Google Docs.

Google Docs support allows you to access your documents from within Cyberduck. It allows you to: download documents to various export formats; upload documents to your Google Docs account for storage or choose to convert documents to Google Docs format; and optionally convert PNG, JPEG and GIF images to Google Docs text documents using optical character recognition (OCR). Users with a Google Apps Premier Account can upload arbitrary files not supported by any of the Google Docs editor application.

Cyberduck 3.5 requires Mac OS X 10.5 or later. It’s freeware, but donations are encouraged to help fund further development.
