Ability to list mxd files which reference a given feature class or shapefile.

Idea created by adrimcm on Jan 14, 2013
    Have you ever inherited a messy directory full of shapefiles and feature classes and wondered how or if they are being used? 

    Wouldn't it make life easier if, via ArcCatalog, a user could select a shapefile or feature class, go into Properties and see the list of .mxd documents (and their locations and last date of work) which refer back to that shapefile or feature class?
