요약

File extensions reveal a lot about a developer's daily life. Opening a clean .json or a well-structured .yaml feels like a small win, while stumbling into a .docx or a legacy .xml can instantly drain motivation. And don't even get started on .heic files showing up where they don't belong. This tier list covers everything from lightweight formats like .md, .csv, and .svg to heavier culprits like .pdf, .psd, and .mov. Whether you live in config files or dread anything that isn't plain text, rank the extensions that shape your workflow and see how your opinions stack up against other developers.
