Unblocking numerous files with sysinternals streams.exe

Problem
After extracting a number of files from a ZIP file windows kept track of these files as dangerous by means of the files ‘stream’ (ie tracking where the file originated from)

Typically to allow these files to execute you need to

Right click the file > properties > UNBLOCK

“This file came from another computer and might be blocked to help protect this computer”

Resolution
The problem was all files were blocked. Resulting in 500 individual changes or…..

To change this (effectivly deleting the stream tracking) to remove the block for all files
Download streams.exe from SYSINTERNALS from here

and then run the following command
streams.exe -s -d %FOLDERPATH%
