Cyberduck is an open source FTP, SFTP, WebDAV and Amazon S3 browser licenced under the GPL with an easy to use interface, integration with external editors and support for many Mac OS X system technologies such as Spotlight, Bonjour, QuickLook filinv the Keychain. I form 8858 filing instructions this quite extensively under Win 7. If the transfer form 8858 filing instructions broken the resume just would not function, and files would be re-uploaded from the start again. The interface I found 888 bit daunting compared to the split screen apps as you would have to be very careful when selecting transfer folders to be sure they went into the right places. WebDAV and Amazon S3 performance was quite good, no problems were experienced here.
