What are the functions of system files?

Windows system files, technically speaking, are any files that have the hidden system attribute enabled. In practical terms, system files are those files that are required for Windows to function properly.

They are used to store critical computer information that, if not present, can cause the computer system to malfunction and fail altogether.

#Hardware drivers, configuration and DLL files, and even the various configuration files that make up the Windows registry are examples of this category.

System files are usually located in a specific folder on your computer's hard drive that has been designated as the system folder. By default, these files are hidden in Windows to further prevent any accidental deletion.
