• VSCode Version:1.1.0
• OS Windows Pro 10.0.10586.318 V1511

Steps to Reproduce:

1. Open with VSCode a text file that has one or more alternate data stream files.
2. Make some small change in the text.
3. Save the file.
4. The ADS files have been removed.

I'm sure that there is a setting that will prevent VSCode removing ADS files when saving — they are, after all, a Windows special. If not, could you please regard it as a bug and add such an option.
