CompleteFTP 8.0 will be released in Q4. It has some exciting new features.
Our DropBox-like client is in beta, and will be part of 8.0. For the first release, functionality is fairly simple but still very useful - the client is a Windows tray app that allows you to select any file to share. The selected file is uploaded via a secure connection, and a unique URL is generated that can be emailed (or messaged) to share that file with others. The URL expires after a pre-set time (or if it is unshared). So basically it allows you to securely share files around the enterprise without relying on a cloud server that the US government is snooping on :)
