I found this a bit odd.

I downloaded submission by Thomas Voetmann and wanted to see what version SW was used. I unzipped and looked at the Last Saved  With column in Windows Explorer and got this...

The computer I used only has SW2013, SW2014 & SW2015 versions installed.

Question, where does the Last Saved With information come from? I assumed it would be embedded in the file header , but apparently not.
