What is a LOG2 file?

LOG2 files mostly belong to Regedit. LOG2 files are specialized files used by Windows to record changes to the system registry.
They work as a registry transaction log by keeping a record of registry updates before these changes are permanently applied. This helps the operating system maintain consistency and enables recovery if a problem occurs during an update.
When the system makes a change to a registry key, the details are first written to this log file. In some cases, tools like regf.exe may be used by experts to analyze these files for troubleshooting or forensic purposes.
Key aspects include:

Logging updates to registry settings

Enabling rollback or recovery of registry changes

Supporting system integrity during updates

FilExt.com note: You normally do not open or edit these files manually because they are meant to work automatically as part of Windows. Advanced tools such as hex editors or specialized registry analysis programs are needed if you must inspect their contents.

A *.LOG2 file is a Windows Registry transaction log file. It stores a record of changes made to the registry, allowing for recovery in case of system failures or errors. The file format is proprietary and primarily used by the Windows operating system itself. These logs are crucial for maintaining the integrity and consistency of the registry, which is a hierarchical database that stores configuration settings for the operating system, applications, and users. This file format is classified as System File.

LOG2 file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. When there is a problem with a file, the first step to solving it is to determine the file format. Our analysis of the LOG2 files produces the following result:

The LOG2 file extension is rather rarely used and mainly uses a special format. The two most common formats are as follows:

90% of all LOG2 files are Windows NT Registry Hive files. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. The files are 8 KB to 1 MB in size, with a median of 90 KB. The file type was developed only in the last few years. The keywords OfRg, regf, rmtm, System and ntuser are typical for these files. The file name ntuser.dat.LOG2 or SAM.LOG2 is typical for these files. These files can be linked to system, class, security, software, user, settings and classes.
