Although these tips from Mind Tools are specifically for filing on your computer [not on top], the same ideas can be used with your every day filing. Whether it be documents, desktop items or anything else that can build up into clutter.
Avoid saving unnecessary documents. Don’t make a habit of saving just about everything that finds its way into your Inbox. Take a few seconds to glance through the content, and save a file only if it’s relevant to your work activity. Having too much data on your computer adds to the clutter that makes it harder to find things in the future – and it may, over time, slow down your computer’s performance too – so be selective about what you keep.
