A quick way to find what you're looking for within a category of files is to number and label your files and make a corresponding index. As an example, I have a section in my files at home called "Important Documents". In a file at the front of this category is an index listing each document and in which number file it's kept. (example: Social Security Cards - File 1, Birth Certificates - File 2, etc.) When I recently had to dig out paperwork on an old mortgage for a class action lawsuit, I simply went to my Important Documents Index, saw that I did indeed have a file on the previous mortgage, and quickly located the document I needed.
