If you're dealing with storage issues while juggling multiple Node.js and Next.js projects, I've found a quick and effective solution: delete node_modules and .next folders for projects not in active development. You can automate it with these commands:

For node_modules: find . -name 'node_modules' -type d -prune -print -exec rm -rf '{}' \;

For Next.js .next folders: find . -name '.next' -type d -prune -print -exec rm -rf '{}' \;
