Thank you for your answers, but I definitely have no virus on my computer.
My question was, when I install paint.net the first time, which files are then in the folder? I do not want to delete and reinstall my paint.net, as I had some other plugins already installed before megalo and I do not want to hate to search for it, find the right version, etc. I have documented, which plugins I installed before Megalo, so best way for me would be to know what is the standard in these two folders after someone has installed it.
And this is my problem. you hat so many plugins I have the feeling it would last my annual leave to go through the plugins. As I do not know the name and as my mother tongue is not English, it is really difficult to find the plugin I'm looking for me and my children.
I was working with photoshop, then I started to work with children many years ago and there we could work with photoshop elements. And there I was used to a plugin base by themes.
A good time ago I started to work in my free time with disadvantaged children. We have donated computers and I changed to paint.net and was happy to find it, as I think you have more possibilities than with photoshop elements and I'm very thankful to the work done here by so many people. My only problem is I think we could do far more, if I would find the right plugins.
And my children love it, too. We have already three of them who got an internship, with paint.net as little reason they have now a good official training space as different craftsmen. The firms had more internships and the children from me showed the master craftsmen, that they could do logos, photos and presentations for smaller regional craft fairs. An having the choice between two trainees which are both good at work, but one can also do presentations, you could guess who was chosen. One cild finished the education for his job and works now self-employed offering presentations for fairs for small firms. He has already two employees.
Therefore I made the suggestion to start a list for the plugins by theme. I just knew and loved this at Photoshop Elements many years ago, when you could buy a version licence. I know the nerds will find any plugin they need, but for the normal people using Paint.net as wonderful software in their free time it is really hard to find the right plugin.
