The config.sys tells MS-DOS which peripherals and devices are installed on your computer. Only in MS-DOS 4.0 or higher, may programs may be started in config.sys.

The configuration file for DOS systems. Whenever a DOS computerboots up, it reads the CONFIG.SYS file (if it exists) and executes anycommands in it. The most common commands are BUFFERS= andFILES=, which enable you to specify the buffer size and the number of files that can be open simultaneously. In addition, you can enter commands that install drivers for devices.

In Windows XP (and probably later versions, but I haven't tried it on those), you would type "msconfig" -- without the quotes, of course.
Editing the config.sys file with a word processor can be dangerous because these applications often introduce formatting characters or hidden metadata that can corrupt the file. Additionally, word processors may save the file in a non-plain text format, making it unreadable by the system. This can lead to system errors or failure to boot, as the operating system relies on the config.sys file for essential configuration settings. It's safer to use a plain text editor to ensure the integrity of the file.
To edit the config.sys file in DOS, you can use a text editor like EDIT or EDLIN. First, open the command prompt and type EDIT C:\CONFIG.SYS (replace C: with the appropriate drive letter if needed). Make your changes in the editor, then save and exit by pressing Alt + F, then select Save, and finally exit the editor. You may need to restart your computer for the changes to take effect.
Both of these are legacy files and not really needed on current operating systems by microsoft. The autoexec.bat starts programs, and ran batch files. The config.sys loaded drivers and configured them.

configsys.exe is used to make some programs on Windows computer to run properly, for example, allows you to use the configuration box without problems. Hence, it is not recommended to remove it from the computer. But sometimes, this process will make the computer to run slowly.

Use the file type test: if [ -d $file ]; then echo $file is a directory elif [ -f $file ]; then echo $file is a file else echo $file is not a directory or a file fi
