amwps If there is a folder mixed with other files, it cannot be scrolled, I use my Android phone to access this link, I can not scroll when entering the directory and back: https://demo.files.gallery/?tests
Shat do you mean "it cannot be scrolled"? And what do you mean "when entering and back" ... Entering that page and back, means you are not in Files app any more.
I already told you, scroll history is almost impossible to integrate properly. Files app is not a "web page" that can just scroll to where it was before. What happens when someone clicks SORT or changes LAYOUT? This doesn't work.
ALSO, you didn't mention what layout you are using. ROWS layout will sometimes adjust height while images load into rows. Therefore, we can't trigger scroll after history, because it's flawed and incorrect. Files app can only scroll the page on history navigation if the page HEIGHT is exactly the same before/after (if not, something changed, or something unloaded changes that size).
GRID and LIST layouts will work better than ROWS because they won't normally adjust themselves while images.
You are the one that asked for this unreasonable request, and this is as good as it gets. Have you seen any other desktop file browser that behaves like this? You are welcome to try to code it yourself or come up with some ideas. Or you can revert to a different non-dynamic page-based file browser. Unicorns don't exist.
