SpaceFix
Review generated data by purpose. SpaceFix separates supported, verified rebuildable items from meaningful history, uncertain files, and protected storage. Cleanup remains an action you choose after the scan.
Four categories worth understanding
| Category | What SpaceFix explains |
|---|---|
| History | Past sessions, logs, and activity data that can grow over time. |
| Cache | Rebuildable files created to help tools load and run faster. |
| Temp files | Short-term working files that may no longer be needed. |
| Build data | Generated files from builds, indexes, and compiled output. |
These names describe purposes. They do not replace an item-level safety decision.
Review Xcode build data before removing it
If you are searching for Xcode DerivedData cleanup, first distinguish generated build output from source projects, archives, and data needed for your workflow. SpaceFix reviews supported Xcode data and classifies eligible rebuildable items separately.
Read the actual finding rather than assuming every Xcode directory is included. Coverage depends on the current app, available access, and safety checks. Keep uncertain items for review, especially when you cannot explain how you would recreate them.
Codex, Claude, Cursor, and package-manager storage
The same principle applies to AI development tools. A tool can produce both temporary material and meaningful session information. SpaceFix’s current site lists supported Codex, Claude, Cursor, and package-manager storage among the categories it can help explain.
Do not assume that conversation history, project work, configuration, or credentials are disposable because they live near a cache. Personal and uncertain files stay outside automatic Safe to Remove.
One cleanup action for verified generated data
- Start a fresh scan and provide access to the folders you want inspected.
- Review supported developer categories and their explanations.
- Keep meaningful history or uncertain findings in Needs Review.
- Use Clean All Safe for eligible items after the review, following any app confirmation.
- Check Trash and rescan to verify the result.
SpaceFix rechecks supported cleanup items before moving them. An item that cannot pass those checks should not be treated as safe merely because a previous scan listed it.
Make storage review part of the workflow
A new build or tool session may generate files again. Compare fresh results when storage pressure returns, rather than trying to keep every working directory empty.
For cache-specific questions, see Mac cache cleanup. For the overall distinction between used and removable space, explore the Mac storage analyzer.
If a build is blocked by low disk space, use the full startup-disk checklist to review storage beyond developer files.
Common questions
Does SpaceFix delete source code during automatic cleanup?
Personal, ambiguous, and protected data does not enter automatic Safe to Remove. Review meaningful or uncertain findings individually.
Does “supported” mean every version of every developer tool is covered?
No. Results depend on app version, the supported locations and rules, permissions, and current files. Review coverage and the explanation shown for each finding.
Less guesswork. One verified cleanup action.
Scan and review first, then use Clean All Safe for supported items. Personal and uncertain files stay separate.
