They don’t obfuscate the filesystem, it’s right there in clear folder trees under each username in the chosen data folder with all the filenames you see in the UI, you can do whatever you want with it.

I hear this bullshit constantly and I go back to check just to make sure I’m not fooling myself and there it is. Where do people get this from, do you not know how to navigate a filesystem?

Owncloud is an enshittified mess. There are very good reasons that Nextcloud hardforked and ran. Stay far away.
