I found a great article on the Wirecutter about organizing your digital files, here's an overview:
It depends on how many files you have, a day to a week.
Start with categories, once everything is filed, file them into sub categories.
Keep in mind to use the same file structure (all singular or plural names, all caps or lowercase). It might be helpful to plot out the folder structure on paper.
Create a main folder called "Projects" and in that folder create subfolders called "Resources," "In Progress," "Final," and "Scrap" to use for the files you create during the process. Also use filenames like "01," "02," "03," etc in folders and files.
Using this structure for your folder allows you to sort by year and search by term: by month, person, or event.
If you are working on a project or frequently accessing a specific folder or you need a folder with a long file path, you can drag the folder over to "Quick Access" on the left sidebar.
Keywords will make files searchable by those terms.
Head over to the Wirecutter for their article on How to Organize Your Digital Files to get more details and examples.
