Copy file with ADS (Alternate Data Streams) via Network loses hidden streams?

2

Thanking to this answer https://superuser.com/a/704697/200806 I discovered ADS (Alternate Data Streams) and started to play some demo: created a test.txt:hidden file with hidden in ADS content. I can see from the same PC where I created it, but when I am copying it over network - hidden content is lost.

Both PC are on Win7x64, target drives are NTFS, connected via Team Viewer VPN (tried both RDP and Share copying - result the same: hidden content is lost)

Is ADS content persistent when copying over network in generally? If Yes Why in my case content may be lost?

I'd gather that Team Viewer stripped it out. I copied several files but without using Teamviewer and the ADS were copied over.

I tried it via Gmail too - the same result. Will try tomorrow on real network. – ALZ – 2014-01-26T10:46:26.240

btw, Skype also cuts ADS – ALZ – 2014-01-27T12:03:20.523

1It makes sense for them to strip it out. There is no guarantee that the destination file system will support ADS. – surfasb – 2014-01-28T00:46:26.577
