What is an SQLITE-SHM file?

SQLITE-SHM files mostly belong to SQLite. The SQLITE-SHM file is a shared memory file used by SQLite when operating in Write-Ahead Logging (WAL) mode.
This file works with your main database file (.sqlite) and the log file (.sqlite-wal) to store temporary data that manages locks and synchronizes access between different database connections.

Role: It holds state information for database locking and coordination.
Creation: It is automatically generated when a database is opened in WAL mode.
Management: The SQLite engine manages this file entirely, and manual edits may lead to errors.

For more details, please see the SQLite official site.
FilExt.com tip: If you need to view it, use a specialized database tool designed to work with SQLite files.

How to open an SQLITE-SHM file

You need a suitable software like SQLite to open an SQLITE-SHM file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your SQLITE-SHM file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a SQLITE-SHM file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert SQLITE-SHM files:

SQLite
See the previous paragraphs to learn more about the main application. SQLITE-SHM files are often referred to as SQLite databases because this type of file is primarily created or used by this software.
SQLite (SQLite Cache file) by SQLite Consortium
The .db-shm file is a shared memory file created by SQLite that contains only temporary data. It is only present when SQLite it running in WAL (Write-Ahead Log) mode. This is because in WAL mode, db connections sharing the same db file must all update the same memory location used as index for the WAL file, to prevent conflicts. SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. SQLite is widely deployed. It is used in many desktop computer applications as well as consumer electronic devices including cellphones, PDAs, and MP3 players. For example, Mozilla's Sunbird/Lightning calendaring programs use SQLite databases. This file format is classified as Database cache.

SQLITE-SHM file format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. Knowledge is power - this also applies when dealing with unknown or faulty files. Our evaluation of the SQLITE-SHM files is as follows:

The SQLITE-SHM file ending predominantly uses a uniform format. The following file formats are most commonly found in SQLITE-SHM files:

85% of all SQLITE-SHM files have the same signature 18 E2 2D 00. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. SQLITE-SHM files can be up to 32 KB in size, but are often around 32 KB - 32 KB. It is a modern file type. Some examples of file names are NoteStore.sqlite-shm or Accounts3.sqlite-shm. Such files are related to store, cache, note, plum, places, model, data, clsbusiness, category, photos and enmap.

The remaining 15% of all SQLITE-SHM files are different files with different signatures. The category is clslocation, storage, database, cookies, media, chat or vsco. Just click the "Choose your .sqlite-shm file to analyze" button on this page to find out what your SQLITE-SHM file is.

How to solve problems with SQLITE-SHM files

Associate the SQLITE-SHM file extension with the correct application.
Update your software that should actually open database shared memory files. Because only the current version supports the latest SQLITE-SHM file format. Search, therefore, e.g. on the manufacturer website after an available SQLite update.
To make sure that your SQLITE-SHM file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
