Hi Bighorn, 
thank you for your reply - tip, much appreciate it. 
Aparently I have over 400 html files in this folder including many subfolders.
In the second one I have close to 200 html files. This year I have to specify each count for the tax.
With simple DOS command dir *.html I do get a list of the html files, but there is no count.
Could you, please, give me the whole command line to copy/paste/?
I am using administrator prompt, have Windows 10 Home 20H2 built 19042.894
The count should be there, but is not. 
Thank you for your help

Here is the last lines of entry, next line is empty and the next line after that is the prompt.
No count.

In your example I do not get past the  dir /o/s/, same as all other examples I found on the net:
Unlike old DOS, the command does not even accept any /  \ (page by page /p for example)
It does not matter if I type /o/s/, or \o\s\ or o\s\. The mistake of a missing back/forward slash makes no difference.
Command just puts it there anyway. I have tried all possible variations.
