From a folder browser (not from Solidworks) If I select more then 3 files in a folder then do *right click* -> "Open" (Figure 1) Solidworks only opens 3 of the files (Figure 2). Is there a magic "open more than 3 files" option checkbox somewhere?

If I do this from within Solidworks using "File" -> "Open..." -> *select multiple files* -> "Open" then Solidworks will correctly open all of the selected files.

Running Windows 10, 64 bit, and Solidworks 2017.
