Seems like you have a permissions issue. I just tested it on Fedora workstation gnome, run it from regular menu, then it asked me for password. You, you have a permission denied isssue, so you need to figure out how to run it as root.

They get better everyday. You will use them at some point if you cannot find your software via your favorite package manager.

I cannot reproduce it, I just tried to copy some files with various methods but they always end up correctly named. The only difference is that I have Btrfs. I never encountered this issue when I was using ext4 though.

Never noticed that? How do you copy them, from terminal? What software do you use? What file system do you use?

There are 2 kinds of distributions. Ones that are on customization side and those on stability side.

For example Debian, Fedora, and arguably Arch are on stability side. They are intended for people that want things to work predictably and software to be packaged and shipped as the developer intended it. Customization or lack of it is up to the user.

Distributions like Manjaro, Zorin OS, Elementary OS, LMDE or even Linux XP are have a given goal to a particular customization. Either a set of tweaks, a particular look or even their own desktop environment or set of software they develop themselves.

This means that the first kind would have the most boring update, as they just ship new and correctly integrated software. While the second kind would provide very nice customisations or patching of their own to their environment.
