Can't open downloded files from Jdownloader on Dolphin KDE

I’m a new user, so I just use the install software app. I created a shortcut (widget).

But I found out that I was using the flappack version, because I searched online and apparently I can’t saved on a external storage.

So I uninstalled and downloaded the aur version. Its working fine now ( I changed the folder to my external storage), but I still can’t access the older files saved on /home.

I guess I was not supposed to save anything there?

I thought the files were occult, but that not it.
