Large does not mean disposable: a size-sorting checklist for Mac projects

I'm part of the GJ File Manager team. Size sorting answers a useful question—what deserves inspection first—but it cannot tell you what is safe to remove. Here is a small review workflow for a project folder with source media, exports and older drafts.

1. Choose size sorting and let any background folder-size calculation finish. A size that is not available yet is not zero.

2. Open a large folder and inspect its contents. A folder named Exports could contain reproducible output, the only final delivery, or both; the name alone is not evidence.

3. For each candidate, check whether it is still used by the project and whether you can recover it from an independent backup. If either answer is unclear, leave it in place.

4. When looking for a recent revision, switch to modification-date sorting and preview the candidate. Modification time is not creation time, and a later timestamp does not by itself prove that a file is the right version.

In GJ File Manager, size sorting and modification-date sorting are different views of the same decision. Neither is a recommendation to delete a file. This checklist does not require an automatic cleaner or a bulk-delete step.

For people working with large media projects: what information do you need before you trust a cleanup decision—project usage, a recoverable backup, a preview, or something else? A concrete example of a file you deliberately kept would be more useful than a space-saved total.
