The future of files

Will the file metaphor die off? Are databases the new filesystems?

File hierarchies are a convenient way to think about organisation, but a tagging system and desktop searching is likely to be the way forward.
I do not, however, think that the file metaphor will die off, even if we had live images, or similar for programs.

That's an interesting issue. Even though everyone is so used to the idea of files and directories, I find them often inadequate when storing thousands of images, many of which could potentially belong to several categories. In this case a tagging system could help greatly, and I've wondered about implementing one myself.
I think we won't ever do away with the idea of a filesystem, but hopefully it will be augumented (or perhaps replaced in some scenarios) in the future.
