Labview Version-Dependent name extention, not just .vi

How come you can't tell which version a .vi was created in until you open it? How come you can't just tell whether it was created for 7.1 or 2010? An idea is to have it save a different .vi extention, much like in Microsoft Office, for exampe, a 2003 version would not open a 2007 version, and you can tell before opening because of the .xls or other extension.  For labview, it could be like for 7.1 it was .vi71 and for Labview 8.2, .vi82, and for 2010, how about .vi2010?

Maybe this could come in handy for those who are looking for certain vi's of a certain version.

Microsoft provides for metadata to be added to file properties.  If you right-click on any file in Windows and click on Properties, one of the tabs is Summary. This would be the ideal place to put version creation information.

 

This is VITAL information.  I have opened a LabVIEW 8.5 file in LabVIEW 2010 by mistake, changed NOTHING, saved NOTHING, and subsequently been unable to open the file in LabVIEW 8.5.   Need I mention it wouldn't work in Labview 2010 either.

Mistercat,

 

You must have actually saved it, whether you realized it or not.  The old file doesn't just get updated and overwritten because you opened it.
