Local File Storage Diagnostics
Overview
Core principle 90% of file storage problems stem from choosing the wrong storage location, misunderstanding file protection levels, or missing backup exclusions—not iOS file system bugs.
The iOS file system is battle-tested across millions of apps and devices. If your files are disappearing, becoming inaccessible, or causing backup issues, the problem is almost always in storage location choice or protection configuration.
Red Flags — Suspect File Storage Issue
If you see ANY of these:
- Files mysteriously disappear after device restart
- Files disappear randomly (weeks after creation)
- App backup size unexpectedly large (>500 MB)
- "File not found" after app background/foreground cycle
- Files inaccessible when device is locked
- Users report lost data after iOS update
- Background tasks can't access files
