Hi Peter
The short answer is no.
The longer answer is "it depends". For a version or two until about Word
2000, Microsoft included a whole lot of metadata in a Word .doc file that
included the version used to create and, if I recall correctly, edit the
document. All you had to do was open *a copy* of the document in Notepad and
view the very end of the file. But if one of those documents was
subsequently edited in a later version of Word, that information was removed
from the file. So its presence may tell you something; but its absence tells
you nothing.
More recently, Microsoft has introduced a new file format for Word, the
.docx and .docm formats. These can (currently) only be created in Word 2007,
but I assume that won't be true for ever. But you can also create an old
.doc file in Word 2007, so not every document created in Word 2007 is in the
new file format.
Hope this helps.
