How are those files? Full of material from 10 years ago. If you haven’t already, now is a great ime to revisit the contents and get rid of anything that is a) not relevant, b) not legally required, c) not accurate.
Remember, not all legally required material has to be kept in your current, day to day files. In fact, material that is several years old and retained purely for legal reasons may be better suited in a long term storage area that is access seldom if ever.
When your done the paper files, start on the e-files.
