A log file is a file that contains a list of events, which have been "logged" by a computer. Log files are often generated during software installations and are created by Web servers, but they can be used for many other purposes as well. Most log files are saved in a plain text format, which minimizes their file size and allows them to be viewed in a basic text editor.
