Taking the time in advance to plan your digital filing system will pay big dividends in the long run. Whether you create emergent files during sessions or work with pre-made templates, having a structure to your filing system will allow you to easily find and file your work.
For example, when I take on a new client, I create a folder on my computer just for them in my Coaching folders directory. Then, I will copy a set of templates into their folder. As I need each template, it’s readily available and I don’t have to explore around my computer (which offers privacy, since I’m usually sharing my screen). Also, copying them to a specific folder all at once gives them the same timestamp, so I can tell by looking at the timestamp which templates we have (or haven’t) used yet.
