Doesn't nextcloud modify files in html/data/%username% ? And how does it work with versions?

Hello, I would like to know if nextcloud modify the uploaded files in the html/data/%username% folder? (for example, does it add some of its metadata, etc.).
In other words, if I ever wanted to take my files from html/data/%username% directly and use them elsewhere, would that cause any problems?
When saving version histories, does Nextcode in html/data/%username% put the latest version of the file ready for use? Or writes the delta of changes there?

Hello @skl256 ,

welcome to the community of Nextcloud.

Nextcloud is not modifying your files. It stores metadata in its database.
You can modify any of your files everywhere you want.

The versioning function keeps all versions of a file in a folder on your server. No deltas are used.
