this question is more of the understanding of .run installation, when you download a file and use .run to install it, does it actually interact with Linux's package manager, or does it work just like a portable program, where once you delete the installation path, it's gone?

For example, if I download Qt Creator which has a .run file, and I install it in Documents/Qt, does that mean it's installed in that path and once I delete that folder it's gone from my system?
