How can you make all types of files show up in Open and Save dialogs? For example: On the Mac, you can be in a Photoshop Open or Save dialog and yet still see all Excel files (and any other file formats) that are in the target folder. (You cannot select and open the Excel files, of course, but at least they show up, which can help you ascertain you're saving to the right place.) Does Windows 7 have such a capability, or is there some add-on that will make such viewing possible? From Explorer, of course, all files are viewable, but I'm talking about a way to view all file types in a given folder from within all applications when choosing Open or Save. Thank You!
