This is interesting. The "tag" is saved in the filename, it appends [tag1][tag2]... to the file name. I certainly don't want that all over my hard-drive, but maybe for some discrete purposes it would be useful. I'd like to see a better description of what it does and how, than I have found so far. I'm so desperate for effective file-tagging (10.6) that I'll try anything :-/ .
