Quick answer: Temporary internet files are web cache. They are usually safe to clear, but site logins and offline data may be separate checkboxes.
Why this uses C drive space
The term is older, but many users still search it when clearing browser or Internet Options cache.
Safe cleanup steps
- Use your browser's clear browsing data page.
- Select cached files only if you want to preserve logins.
- Use Windows Internet Options for legacy cache if needed.
- Restart browsers after cleanup.
- Check storage again after cache rebuilds.
What to avoid
Do not clear cookies and site data if you need to stay signed in.
