Michael Jumper created GUACAMOLE-326:
----------------------------------------

             Summary: Alternative streams on Windows 10 result in multiple file downloads
                 Key: GUACAMOLE-326
                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-326
             Project: Guacamole
          Issue Type: Bug
          Components: RDP
            Reporter: Michael Jumper
            Priority: Minor


When a file has been downloaded over the internet via Windows 10, and that file is later transferred over Guacamole using the magic "Download" folder, multiple files end up being transferred: "filename.ext" and "filename.ext:ZoneIdentifier".

This is due to the way Windows 10 tags files downloadded over the internet with secondary "streams", such that it can warn users of the risks prior to executing those files:

As Guacamole does not actually use such files, and the underlying filesystem does not support them, they should be appropriately ignored/rejected rather than downloaded.
