SQLite Data
Disk & DatabaseSQLITE is a suffix used for SQLite databases. Inspect schema and producer requirements. A live database may have WAL companions; copying only its main file can omit current changes.
- What it is used for
- Embedded databases with tables and indexes
- What the file contains

Menu labels and support vary by app, OS and version. Preserve the original before making changes.
Troubleshooting by symptom
- Database locked: inspect producer activity; do not delete WAL/lock-related files to force access.
- Stale copy: use the producer’s supported backup or SQLite backup workflow for live data.
- Not a database: inspect completeness, encryption or a proprietary format; the suffix alone is inconclusive.
- File is not a database: investigate another format, encryption or damage with the producer.
- Recent data missing in copy: inspect WAL state and the copying method.
- Lock error: inspect active applications/access methods rather than deleting related files casually.
SQLite → CSV / SQL backup
- Inspect tables/columns in a read-only copy and export the intended data.
- Check types/NULL/encoding for CSV or schema and restoration results for SQL.
- Compare counts, nulls, text and numbers and preserve the database/schema.
CSV does not preserve indexes, constraints or relationships; table export differs from backup.
Main database, WAL and backup
WAL mode may record updates separately. A live copy of the main file alone is not necessarily complete.
Use a supported application/SQLite backup method and inspect the resulting copy.

Integrity versus semantic correctness
Run integrity checks such as quick_check on a copy when needed; structural integrity is separate from intended data correctness.
CSV may not retain types, BLOBs, nulls or relationships. Preserve the database and schema.

Related-format differences
| Format | Main role | Selection notes |
|---|---|---|
| SQLITE | SQLite database file | Inspect a consistent copy |
| SQL | Commands / dump | Not the database file |
| CSV | Tabular export | Inspect types and relationships |
Handling and security
Databases may contain credentials or personal history. Review tables before sharing and avoid executing unfamiliar SQL.
Questions and answers
Can I delete the WAL?
It may contain uncheckpointed changes; follow supported backup procedures.
Is CSV a complete backup?
No; it does not preserve the complete database structure.
Can renaming to TXT make it readable?
No; use SQLite-capable tools.
Can I rename SQLITE to SQL?
Database storage differs from SQL text. Export through a dump operation if required.
May I delete the WAL file?
It can contain pending data. Follow the application/SQLite backup process.
