Thanks Michael.

What to my supprise is not only the directory (.zip or .tar). The tramp should not be loaded for local folders or files. Is my understanding correct?

Now I can open the folde with ext of .zip or .tar. It still trigers the load of tramp.

And I try to open a local zip file. The file can be opened however it has the message "Error: (user-error "Package `tramp-archive' not supported")".

Sorry not test it last time.

Same here, under GNU/Linux. However, why do you create a directory ("a
folder") with the extension .tar or .zip? These are intended as "file"
name extensions, not for directories.

Anyway, I've committed a patch to the master branch, which should fix
this. I hope this does not delay file archive operations too much,
because for every single magic file operation I have to check now,
whether the file archive is a directory.

Could you pls check whether this works for you?
