Is there any way to delete or hide all the 16 more recent documents list when I hit "File"?
It would be very helpful!
That is basically just a "shortcut" way to get to the files - just a reference. It does not have file management capability (deleting, etc). You could enter an enhancement request for it.
If you are running SW13, before starting a new session of SW, run the attached regedit file. It will strip all the recent doc's listed in the registry key at HKEY_CURRENT_USER\Software\Solidworks\SolidWorks 2013\Recent File List
Having an "on the fly" reset option would be nice though.
If file open in notepad and replace "2013" to "2017", works fine for sw2017.
