Organize files with folders

My project folder is a mess after last semester. Put the course notes, assignments, and grading spreadsheets into a single top-level folder named Spring 2026 — inside it create Course Materials, Assignments, and Admin. Move the files I uploaded between March and May into the right subfolders, but keep the original filenames and timestamps. Tell me what moved and if anything failed.

Before I hand this folder to the research team, make it quick to scan. Put a one-page index at the top of Spring 2026 listing each subfolder and three representative filenames, surface total size and last modified date, and flag any files larger than 50 MB or whose names contain 'draft' or 'final' inconsistently. Suggest three filenames to make versions obvious.

I accidentally replaced March_notes with an older copy and lost recent changes. The team lead is on deadline and will assume I messed up tracking versions. I can’t tell if anyone else edited those files or where the latest material is. Do I restore from a previous version, contact the team and admit the overwrite, or try to recover specific files first? Recommend the fastest least-damaging step and the next communication I should send.

Every project I manage ends up with ten duplicate folders and conflicting naming conventions, and people attach files in email instead of the shared folder. I lose time merging duplicates and explaining the structure. What three habits should I change immediately to keep one clean folder system, and what two onboarding lines to tell collaborators so they follow it without nagging?
