Jeremy Mazner has a good post on why Microsoft is building WinFS, the new file system for Windows that will debut with Longhorn. The file/folder structure was good when hard drives were a few gigabytes, but when begin to get into the terabyte range, it starts to fall down. It’s like my personal (paper) filing system. At the moment, I have a few documents I need to get my hands on, so a few drawers will do – or, in my case, a cork board with lots stuck to it. As the nnumber grows, so that system starts to fall apart.
