What is a .REGTRANS-MS file?
The file extension .REGTRANS-MS stands for Registry Transaction Log File. This type of file is created by a part of Windows called the Microsoft Common Log File System (CLFS). The purpose of the CLFS is to help manage transaction logs, which are records of changes made during a process.
A .REGTRANS-MS file specifically contains information about changes made to the Windows registry. The Windows registry is a database that stores settings and options for the operating system. This file tracks both read and write operations that alter registry data related to user settings or system configurations. The changes are usually linked to two important files: NTUSER.DAT, which holds user-specific registry data, and SCHEMA.DAT, which contains system-related registry configurations.
These .REGTRANS-MS files are part of a larger system that includes another type of file with the .BLF extension. Together, they make up the complete transaction log that helps Windows restore or revert registry data to a previous state if needed.
You can find .REGTRANS-MS files mainly in two locations on a Windows computer: 1. C:\Users\[user]\ - This directory contains the registry data specific to each user on the computer. 2. C:\Windows\System32\SMI\Store\Machine\ - This directory holds registry data that is used to restore the system's settings.
To open or manage .REGTRANS-MS files, you typically don't need any special software because they are handled by the Microsoft Common Log File System, which is included with the Windows operating system. However, these files are generally not meant to be opened or edited manually, as they are part of the system's internal operations.
