An interesting site I stumbled across while researching Windows relics--DOS--showed me another trick that I has heard of but never delved into: alternate data streams on NTFS. Alternate Data Streams are a lesser known feature of NTFS that has been taken advantage of by occasionally less than ethical folks. Shortly after exploring ADS I began exploring the use of this and found that ADS software is hard to program. It is also being outmoded by Vista. Nonetheless, it was a cool read.
