This device manages the rest of memory. This device operates the CD drive. This file does optional tasks like loading programs that you want to start every time your computer is turned on. You may see a lot of messages on the screen as the various programs are started. This file also tells the computer where to look for files, called the path .
Many programs add their own directories to the path when they are installed.
Here's an example of an autoexec.bat that might be used under Windows 95, with explanations on the right in blue. The blue parts can't be in the real file. Win95 doesn't require an autoexec.bat but you might want to change some of the defaults or to have some things to run in DOS mode. This is a remark. If a line starts with REM the computer ignores the rest.
