I thought streams were small bodies of water that flow through the forest, sorry couldn't resist :) This really software really is helpful in finding and seeing data that was cleverly concealed until using this. Thanks for some helpful software another hit from Nirsoft, keep em coming please.

Dropbox had a bug a while back ( and polluted every file with an alternate data stream. Any copy action thereafter from our NTFS drive to a thumb drive (usually FAT32) was interrupted by a warning, "Are you sure you want to copy this file without its properties?" Very annoying! AlternateStreamView quickly and easily fixes the problem, as discovered here (

@ vmars316: Alternate (Data) Streams are a data structure for holding additional structured data within a file in addition to the main data.
The Windows NTFS file system allows so-called Alternate Data Streams (ADS). With this function, data can be stored invisibly tied by the user to a file.

What is an "Alternate Stream" ?
Are you talking about 'streaming video' ?
