Problems with Joplin Portable

I’m new to Joplin and am evaluating the Windows Desktop Portable Version and was about to post a new topic “Is JoplinPortable really portable?” when the sidebar found this topic which has had no reply in 14 months

When first run it creates it’s JoplinProfile folder tree next to itself on the USB drive BUT it also creates a Joplin folder tree in AppData\Roaming which means it isn’t strictly portable.

See https://en.wikipedia.org/wiki/Portable_application extract “storing its program files and any configuration information and data on the storage medium alone

Please may msel and I have your thoughts?
