Cookies: are .xml files considered to be cookies as well?

Likely a 'newbie' question.

 

Just out of curiosity...

with CCleaner->Options->Cookies open I used an other tool to clean cookies and see what what would happen, i.e. if all cookies were gone.

 

The other tool showed no cookies anymore, however, CCleaner still showed some 40-50 entries.

 

After checking further I discovered they mostly, if not all, referred to .xml files in Internet Explorer (v11)

\Domstore folder

(In Domstore the same entry maybe listed twice or more but in different subfolders)

 

 

Q:

I believed cookies were .txt files only?

Is it correct to list .xml files as cookies as well?

Maybe it is, I don't know.

 

Thanks.
