Home > Windows files
File Overview
Here is an overview of the best-known files - from Windows 10 to Windows XP. (There are also a few files that date back as far as Windows 3.1, like notepad.;-). Please be aware that some software products use the same file names for completely different files. Even viruses often try to conceal their identity by using the name of a common system file. This a not just a security threat - it can also lead to other types of problems. Accordingly, for each file, you will find not only a technical analysis of each of the variants, but some user comments as well.
