A clean rewrite of the Filer for helloSystem (but not limited to it), inspired by John Siracusa's descriptions of "Spatial Orientation" and the Spatial Classic Finder (Video).
To try it out, run the latest experimental helloSystem ISO build and press the "V" key for verbose boot (this will cause this new, work-in-progress Filer to be loaded).
- No GLib dependency
- No libfm dependency
- Minimal dependencies other than Qt
- No inherited code
- Uses launch "database"
- Runs on FreeBSD (developed for helloSystem) and on Linux (occasionally tested on Lubutnu)

| Use technical jargon like "executables", "files", "directories", "properties", "wallpaper" | Uses familiar desktop terminology like "applications", "documents", "folders", "info", "desktop picture" | DONE |

DONE |
When you double click an application and it fails to run, nothing happens because the error goes to /dev/stderr, which is invisible |
When you double click an application and it fails to run, the error is shown in a dialog on the screen | DONE via launch |
| Are not optimized for managing and launching applications | Is optimized for managing and launching applications | DONE |
| Cannot rename disks | Can rename disks | DONE via renamedisk helper command line tool |
| Do not have spring-loaded folders | Has spring-loaded folders | DONE |
| Use Gtk-centric dependencies like Glib, Gdk, Gio, polkit | Does not use Gtk-centric dependencies | DONE |
| Refuse to copy/move/delete items which the user doesn't have access to | Asks user for root password to copy/move/delete items which the user doesn't have access to | DONE for copy/move, TODO for delete |
Use weird locations like computer:// and network:// that are nowhere in the filesystem |
Uses proper paths in the filesystem for everything | DONE |
My conclusion is that most "desktop environments" are made by people who don't actually love the desktop. Or else, those basic things would work.

Q: Can this run on Linux?
A: It does build and it can run, but in order to give the full experience, you might want to consider using helloSystem, which comes with additional tools and careful preconfiguration to make Filer work as intended.
