Stream Explorer is a utility that reveals file streams with Windows NT 4.0, 2000, XP, 2003, Vista or Windows 7.

Stream Explorer will show you the number of streams in each file as they are listed per folder.

When you select a directory entry, Stream Explorer will list all the streams in that entry, and you can see their type, their size and contents. The unnamed stream is shown as <default>.

This new version will show streams in folders as well.

Stream Explorer is freeware.
