Importing Files by Polygon

Is there a way to import/load only the files or data that spatially intersect a selected polygon? I have a large volume of files with varying tiling schemes and would like to process them into a new scheme (generate DEMs, etc...). The files are large so I only want to load the pertinent files to maximize computing efficiency.

Any help would be much appreciated.

    While you can't directly do that, you could use the File->Create New Map Catalog menu command to create a map catalog from your large collection of files, then just those files will be loaded when you zoom in far enough. That way files that you don't use don't have to be loaded.
