Please add metadata details associated with Mathcad files. The only way to index Mathcad files is to put them in folders and change the file name. If metadata details were added to the files, more information on what the file contains can be added. This becomes searchable and sortable in Windows. The feature is inherit with mp3 files which lists a wide array of fields that can be associated with the file. This makes cataloging, searching, and sorting my mp3 library a breeze in Windows. If Mathcad had this feature, archiving and retrieving my work could be just as easy. Thank you.
