What is an appropriate next step if disk space remains low after cleanup?

Correct answer: Identify large unnecessary files and remove or move them to external storage

If routine cleanup does not provide enough space, the next step is to inspect storage usage and locate large, unnecessary files such as obsolete downloads or duplicate media. Their importance should be checked, and important data should be backed up before deletion. Files that are still needed can be moved to reliable external storage. Password removal, extension changes, or deleting a mouse driver will not meaningfully solve low disk space.
