How do I stop ".2" from being a recognizable file extension?

I do land research for a living. When checking taxes, I save my files with .1, etc. to identify which half or quarter the bill is referencing. For example, for quarterly taxes from 2020, my files would be 2020.1, 2020.2, 2020.3, and 2020.4. These are saved as .pdf files and I do them rather rapidly. Lately, however, when I type, for example, 2020.2 and hit enter, the file is named 2020.2 instead of 2020.2.pdf. Then I have to go in and rename the file. It's just an inconvenience, and I realize that. (It's much easier than having to rename every scanned file because the printer programs all add a date or other "addition" to the name I choose...but I digress.) Anyway, I'd like to be able to type "2020.2" where it will save as "2020.2.pdf" just like "2020.1" saves as "2020.1.pdf". I don't believe I use any files with a ".2" extension. Thanks :-)

    known file types are under the HKEY_CLASSES_ROOT key in the registry.
    So if you find "HKEY_CLASSES_ROOT.2": renaming or deleting the ".2" key should help.
