Description Alex Kh 2022-11-17 21:58:01 UTC 
I'm running KDE Neon unstable with all the latest updates in a virtual machine, but I've seen the same behavior in couple of other distros, like Ubuntu 22.10, Manjaro, Pop OS - you name it. 

STEPS TO REPRODUCE
1. Be logged as a user to whatever desktop environment, not as root. Tested with XFCE, Gnome and KDE. 
2. Open Filelight and scan a root folder
3. Go into some directory, 2 or more levels behind /, like /usr/share

OBSERVED RESULT
In a piechart you'll see a portion, attributed to the current user home directory. Even the tooltip says the same.

EXPECTED RESULT
No extra piechart portions, which have nothing to do with a directory, where the user is, should be displayed. 

SOFTWARE/OS VERSIONS
Linux Neon Unstable 22.04 x86_64 kernel 5.15.0-53
KDE Plasma Version: 5.26.80
KDE Frameworks Version: 5.101.0
Qt Version: 5.15.7

Fix the path shown for unrepresented files

To represent the bunch of smaller files, we use a fake `File`
with a custom string as the filename.

Add a specific subclass for this case, where we also set the
parent `Folder` so the right path is shown. Otherwise,
`File::displayName()` will show the current working
directory as the path for our fake item.
FIXED-IN: 22.12.0
