What is a HISTORY file?
A .HISTORY file stores a record of past events or actions for a specific software application. Most often, this file is an SQLite database used by web browsers or software applications to keep track of user navigation, messages, or software events. However, a .HISTORY file can also be a plain text file, an XML file, or a UTF-16 encoded log. For example, software like IObit Uninstaller and Spybot - Search & Destroy use .HISTORY files to track uninstallation logs. The Z3X Samsung Tool uses them to log phone servicing operations, and Unix C Shell environments use them to record terminal commands.
How to open HISTORY files?
Because a .HISTORY file can use several different formats, the correct software depends entirely on the file creator. If the file is an SQLite database, you can open it with a dedicated database reader like DB Browser for SQLite or command-line tools. If the file is plain text or XML, you can open it with a text editor like Notepad++.
viewer.online/history analyzes .HISTORY files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because .HISTORY has multiple possible meanings and data structures, we highly recommend using viewer.online/history to identify the actual format of your file.
Best practices and troubleshooting
Do not edit a .HISTORY file directly if the parent application is currently running, because this can corrupt the SQLite database. Always make a safe copy of the file before you attempt to open or extract data from it. If your standard text editor shows unreadable characters, the file is likely a binary database file.
Software and tools
Software that creates or manages these files includes SQLite, basic text editors, Spybot - Search & Destroy, and IObit Uninstaller. If you need to convert your file data for spreadsheets or reporting, we recommend file conversion to sensible target formats like .CSV, .JSON, or .TXT on convert.guru.
Summary
Because .HISTORY files use the known SQL format, viewer.online/history can safely open and display them online, eliminating compatibility problems.
