Extract text from SQLite shared memory files (DB-SHM)
To convert DB-SHM shared memory files to another format, you need SQLite or other Database software.
To convert other file formats to the "SQLite WAL Index File" file type, you need software like SQLite or a similar tool.
A .db-shm file is an SQLite Shared Memory file. It functions as an index for the Write-Ahead Log (db-wal) when a database operates in WAL mode. This file tracks which database connections are reading or writing data, ensuring concurrent access does not corrupt the database.
Because a .db-shm file is purely a system-level index, it presents major challenges for regular users. It is entirely proprietary to the SQLite engine and contains no actual user data, text, or tables. It only holds volatile memory state information in binary format. Standard online converters fail to process .db-shm files because they lack the database schema and records, which are stored exclusively in the main db or sqlite file.
To view or extract your data, you cannot directly convert a .db-shm file to CSV or JSON. Instead, you must keep the .db-shm file in the exact same folder as its parent database and open the main file using software like DB Browser for SQLite. Once the main database successfully loads the shared memory and WAL files, you can export the tables to CSV, JSON, or SQL. If our analysis detects any recognizable embedded strings, viewing the underlying structure may still be possible.
Convert.Guru analyzes your DB-SHM file, detects the exact format, and lets you read the text inside.
Users also converted DB-WAL, DB, CHAT, PLIST, TEMP, SQLITE, PB, BIN, MOM, DATA, TXT, MOBI and ZIP files.
If you want to convert DB-SHM file to DB, SQLITE, SQLITE3, MDB, ACCDB, DBF, ODB, FDB, GDB, MYD, FRM or SQL, you can use SQLite or similar software from the "Database Shared Memory Index" category. In the File menu, look for Save As… or Export….
To convert NDF, SQLITE3, BAK, RDB, SQL, DB4, MDF, MDB, LDF, DB, DB3 or SQLITE files to DB-SHM, try SQLite or another comparable tool in the "Database Shared Memory Index" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DB-SHM converter.
