Files missing in conf folder after successful installation of openHAB 2.5

Platform information:
Hardware: Raspberry Pi 4
OS: Raspbian Buster
openHAB version: OpenHAB 2.5
OpenHAB web interface is built on files like items, sitemaps and rules. To make my own sitemaps and items file, I am using Visual Studio code. In the openHAB conf folder, the files should be present for editing, to configure the OpenHAB interface. But after successful installation of openHAB 2.5, the demo.sitemap files are not present in the openHAB- conf folder, only the readme.txt is available

kindly help me on this issue.

Did you install the demo? Most people choose “Standard”

Here is the sitemap tutorial.

I have the same problem, with the same installation type en software version.
I can navigate to the ip address of the pi, but there is no folder available.
I have checked the folders in de samba en gave browse permission tot the home folder but no difference.
I work also in the demo setup.
