We’ve just updated our Labs page with the beta 4 of our Mac Drive. This is a huge step forward in our goal of having a robust multi-cloud drive for the Mac OSX. We now have implemented a cache to keep Finder happy when files are first copied or dropped there, and we add them to a queue so that they are uploaded in the background. If you shut down then the files resume next time you fire up the laptop and the drive is mounted
We also catch queueing operations so we can deal with renames and deletes, and we also now support the opening of encrypted files as well as letting you get a URL for a file using Finder Service actions. You can watch the video below to get more of a feel for what the drive does.
