The lgl file extension is used by Microsoft Windows for generated application logs.
In Windows 98 and Windows Me, the Task Monitor tracks which programs are launched and how they load from disk, and it records the info in the Applog folder.
The Defrag utility then uses this info to provide special optimization for the program files you use most often. Rather than rearranging the clusters of these files in sequential order, Defrag rearranges them in the order they're loaded when the program launches.

LeechGet uses LGL files to save download queue information, allowing queued downloads to be retained between sessions. The file belongs to the application's queue-management data rather than to the downloaded files themselves.
LeechGet was discontinued by its developer. Although it may still be available from Internet download archives, the LGL format is associated with the discontinued Windows software.
Open an LGL file with LeechGet on Microsoft Windows. The file is intended to be loaded by LeechGet as a download queue rather than opened directly in a text editor or general-purpose application.
LGL files are application-specific queue files and do not have a useful general-purpose conversion format. To preserve the queued downloads, open the file in LeechGet.
