What is a LG1 File Type?
It allows applications that run on separate servers and at different times to communicate with each other. The quing allows you to store messages in a queue in case an application receiving a message from apos is currently inaccessible. When the application becomes accessible, the waiting messages are sent to the application. An example of this is in electronic commerce, where sales have to be handled by different applications on different networks.
Messages between applications are stored in the MQ files. These files may contain messages from one file of waiting or several files of waiting. The size of the MQ files is up to 4MB, then another MQ file is generated. Since the messages can occur over a long period of time, information is written in LG1 and LG2 to save the file; status of the file MQ in case something happens to it.
You will probably only encounter an LG1 MSMQ file if you are a developer of a system that uses MSMQ and you explore the MSMQ\ Storage folder. It also contains one or more MQ files for which LG1 and LG2 files were created to store logs.
The MSMQ protocol was developed by Microsoft and introduced in Windows NT 4 and Windows 95.
