Expo HAS CHANGED

Read the exact versioned docs at https://docs.expo.dev/versions/v57.0.0/ before writing any code.

Local storage

Persistence is SQLite-backed via services/sqliteStorage.ts (expo-sqlite, database dot.db).

Tables: folders, files, user_preferences (schema migrated via PRAGMA user_version).
Folder and file per-row sync status: local | cloud | local-cloud.
services/localStorage.ts is a thin re-export of sqliteStorage for legacy imports.
Query usage: getFiles(folderUri?), getFolders(), getFolderFolders(parentUri), saveFolder, saveFile, saveUserPreferences, getUserPreferences, removeFolder, removeFile.
Heavy processing stays server-side; SQLite only persists local metadata/state.
