Do you know what are NTFS Alternate Data Streams? If not, look at Accessing alternative data-streams of files on an NTFS volume, a Richard Deeming article. There you can download the sources and binaries of the NTFS.dll used in my project.
This project is a Windows GUI extension that allows you to Find and Remove all the interested data streams stored on your local drive or a network folder.
The data is returned in a DataGrid and you can sort it by stream name, size, location and file name.
The core of the form uses a recursive search, and each file found is stored into an ArrayList, and so is all the streams information of the file.
