Using File Properties
Finding files can be difficult on computers you share with your colleagues or if you’ve been using the same computer for a long time and have created a lot of workbooks. You can make it easier to find your files by describing them in the Properties. If you enter a term in a Properties field, you will be able to search using that term, even if it doesn’t occur within the body of the workbook.
