Is it possible to link a variable to a windows file property?  I want to create a "last modified" property for some miscellaneous files that will not be under strict revision control, and to which enterprise has no access to custom properties (e.g. pdf files).  Is there a way to link a variable to the "last modified" date that windows keeps track of.  I can see it in the explorer view, but I can't figure out how to get it on a data card.

  Any suggestions?
