Thank you for the hint scorpio810. I shared the diagnosis of how I found it.

~/.qet does not exist. I used a snap, and have no idea how snaps work.

I am using manjaro linux. There is nothing in the AUR, but there is a SNAP. I am not familiar with SNAPs. What is the default user collection directory path? The Configure QElectroTech GUI does not list the current path, only "Default". I need a few objects that I created at home to go to my work.
