Essentially it's an aggregator of file metadata from multiple sources. Accessing the local database can be a lot faster than accessing the data where it actually lives. It also allows for offline access if the device containing the files is temporarily removed. (Well, by access I mean previews and metadata.) For example, I have a gigabit LAN with a Synology NAS, a server with a bunch of hard drives, and various networked machines. Gigabit LAN is pretty slow. Getting image previews of RAW photos on the NAS is insanely slow and frustrating. With something like SpaceDrive, you have basically instantaneous access to those previews, metadata, and Everything-like (the Windows application) search capabilities. I'm really excited about it! I have files strewn about in so many places. Having access to them from a central location, with a single interface, not relying on a slow network, is really great. I might even go crazy and start to organize things with tags.
