I can't make HTML with AMP pages a copy of a site with XAMPP - the name of the folder and file are the same. What can be done?

Question

HTML

Greetings! I decided to try out what AMP pages are on a WordPress site that runs in XAMPP. I generate a local copy of the site with the Simply Static plugin and upload it to the hosting. And I decided to try out the beast "AMP accelerated pages" on it. I installed the AMP plugin, which generates pages with the /amp/ prefix . Those. regular page http:\site.ru\samplename.html and its AMP page http:\site.ru\samplename.html\amp\ But I can't make a local copy: the plugin creates a local copy of the page, for example, http:\site .ru\samplename.html and can no longer create the samplename.html folder (writes Unable to create temporary directory).
What do you advise? Maybe in htaccess somehow make a redirect so that the root html is saved in a subdirectory like that?
