.r35, .r36, ... not associated with WinRar = no icon

I have .rar files associated with Win rar, except that after about file .r35, the association stops. While the first file (.rar) does set off the whole chain, the lack of association is a bit troublesome, as the ability to scan the icons helps file selection. I can set the association manually (Open with -> more apps -> winRAR). However, that is 65 or so files, plus occasionally the file extensions drift to .s01, s02 ... and presumably .txx, .uxx, etc could follow (don't think I've seen it go that far, but as said, the WinRAR does find its own way)
Some sort of 'batch association' would be the simple. Googleizing the problem brought up "Types is a free and lightweight configuration utility" but it doesn't seem to be out there any more (WinXP era).
Any ideas?

They are not associated asyou cant generally open them on there own as they contain only a small part which on its own can be useless you have to open the rar file for it to work

See is this can help.

Settings>Apps> Default apps>Choose default apps by file type>or protocol>or Set defaults by app

Correct.

And what would be the point associating every possible rar suffix?

The suffixes run from .r00 to .rXX ... because a given rar archive can be divided into many pieces, each with its own suffix.
The only program that "cares" about the suffix is your rar archiver ... which will respond when you click on a .rar or .r00 file ... and will then proceed to read all of the .rXX files.

Humans need not care about all those numbered suffixes.
