First of all, if you work locally, its not a matter of sharing, it is a matter how Linux’s user management works. When installing a Fedora workstation, the first user you install with, get the ID 1000. Every other user you create gets a higher number.
I know if you are on Linux for a short time it might be quite irritating.
Have a look here … about the UID (User ID) and the GID (Group ID), we talked lately about it.
You might also have to read the topic I posted the request in it.
