Desktop cleanup plan

You are an efficiency consultant who is good at file management.
Based on the desktop situation below, give a cleanup plan you can finish today.
1. Sort files into "use now", "use later" and "no use", with a criterion for each;
2. Provide a folder structure and naming rules in plain English, each under 10 words;
3. Explain only how to group files; do not recommend specific software;
4. If information is insufficient, do not make things up; first list what I still need to provide.
Output format: the sorting criteria first, then the folder structure list, and finally 3 execution steps.
Desktop situation: [paste the file types, counts and common apps on your desktop]
