Folders are a good tool, but once you create more than one level in your hierarchy, you are lost and you end up searching documents by text patterns. Still, a single level folder system works, especially if all folders somehow fit your screen so that you can see all at once. Leaving only search/tagging is an extreme and I think developers will eventually come to the idea of one-level folder system combined with optional tagging (i.e. you tag only if a word can't be found in the document but you feel it's relevant).
