What is an SQ file?
The .SQ file extension connects to several different software formats. Most commonly, it acts as an SQLite version 3 database. Developers use these files to store structured data locally in a lightweight, self-contained database format.
Because the .SQ extension has multiple uses, it can also serve as a volleyball team roster file created by Data Volley or TBT-Team Volleyball Software. Additionally, .SQ files appear as metadata for PVR recordings in MediaPortal or Topfield PVR, speech sequence files for Adventure Game Studio, music sequences for Square Enix games, or Sysquake program scripts.
How to open SQ files?
If the .SQ file is an SQLite database, you can open it with a command-line tool like `sqlite3` or desktop applications such as DB Browser for SQLite and DBeaver. For volleyball roster files, you need Data Volley. For PVR recordings, use MediaPortal.
Since you might not know the exact format of your file, viewer.online/sq analyzes .SQ files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
Do not edit database files in standard text editors. This action can corrupt the internal index structure. Always use dedicated SQLite tools or specialized hex editors.
If you suspect the file is a sports roster or a game sequence file, check the file header to identify specific text strings before trying to open it in a specialized application.
Summary
Because .SQ files use the known SQL format, viewer.online/sq can safely open and display them online, eliminating compatibility problems.
