Just came across this problem, to use a Microsoft tool, can be in C # code through the process, the command line execution of this tool, you can unlock.

Using Streams

Usage:streams [-S] [-d] <file or directory>
-srecurse subdirectories.
-ddelete streams.
Streams takes wildcards e.g. ' Streams *.txt '.
