Here is a very extended alphabetical list [including niche formats and obsolete ones, propriety files and file languages originating from variety of platforms thus not limited only to Windows] of all kind of file extensions associated with
configuration / settingstype of file formats
First version of the list is horizontal and ready-to-use in Everything for the feature of Filter available in it under the
Search > Add To Filters... > Search
Search > Organize Filters... > Edit > Search
The second version is also horizontal but made with a purpose of being easy-to-read-through. The third and last one is vertical and is suppose to ease up manual finding or comparing extensions. [You can change appearance of those list using simple replacement feature available in probably every text editor; or using advanced line operations in free editors like Notepad3 or Notepad++; or using most complex of them all some regular expressions]
Fell free to post new complementary formats and / or comments about mistakes on this list
