Other File Extensions Similar to LOG
While LOG files are commonly used to track events and store information, there are other file extensions that serve similar purposes. In this section, we will explore two such file extensions – Hive LOG files (LOG1, LOG2) and LGO files – their characteristics, and their applications.
Hive Log Files (LOG1, LOG2)
The Windows Registry, a crucial component of the Windows operating system, uses Hive LOG files to keep track of changes made to the registry. These files come in the form of binary files and are named LOG1 and LOG2.
Let’s delve into the details of Hive LOG files and their significance. 1.
Binary Format: Hive LOG files are stored in a binary format, which means they are not human-readable like plain text LOG files. The binary format allows for efficient storage and retrieval of registry data.
2. Windows Registry: The Windows Registry acts as a hierarchical database that stores settings and configurations for the operating system, hardware, software, and user preferences.
The registry is organized into multiple hives, each serving a specific purpose, such as user settings or system configuration. 3.
Config Subfolder: The Hive LOG files, LOG1, and LOG2, are located within the Config subfolder of the Windows System32 folder. This subfolder contains important configuration files and log files related to the Windows operating system.
The significance of Hive LOG files lies in their ability to track changes made to the Windows Registry. During normal operation, the LOG1 file is actively written to, preserving a record of registry modifications.
Once the LOG1 file reaches a certain size or Windows is shut down properly, it is renamed to LOG2, and a new LOG1 file is created to continue logging changes.
LGO Files
In contrast to the binary Hive LOG files, LGO files are associated with the Logo programming language. LGO files contain program code written in Logo, a language primarily used for educational purposes and teaching principles of programming.
Let’s take a closer look at LGO files and their usage within the Logo programming language. 1.
