I want to have my macro code determine the date a file was last updated and
then from there, decide whether or not to open it. What I don't know is how
to access the file's property that returns that date it was updated. If I
could just use an "If" statement to say something like this, in principle:

If Filename.DateUpdated = Today() - 1 Then
Workbooks.Open Filename
End If

The goal is to only open files that have been updated within the last two
days. Is this possible?
