How do I handle different file types on Android vs iOS?

This skill provides specific mappings for the FilePicker, using MIME types for Android and UTType identifiers for iOS and macOS to ensure consistent behavior.

Does this skill handle photo and video capture?

This skill is designed for general file handling. For specialized media capture or photo gallery picking, you should use the maui-media-picker skill.

Can I modify files directly in the Resources/Raw folder?

No, bundled assets are read-only at runtime. This skill provides the standard pattern to copy assets to the AppDataDirectory if they need to be modified.

Why use OpenReadAsync instead of the FullPath property?

On many platforms, files are returned as content URIs rather than traditional file system paths. OpenReadAsync is the recommended, reliable way to access file content across all platforms.
