  • Network shares are practically untested, and unresolved network shares can freeze the application UI for some time.

You use the application at your own risk. I can't be held responsible for any damage that it might cause to your files or your computer.

Imperium is free to use and distribute, for both private and professional purposes. However, you may NOT sell it for profit.

Imperium borrows some core concepts from other file managers, and attempts to improve upon them.

Most notably, Michael Herrmann's fman is what initially sparked me to start this project.

Imperium is currently available for Windows and Linux, and should run fine on most laptops.

Note that the application has been tested only on Windows 10 and Ubuntu 20.04. It might or might not work properly on older Windows versions or other Linux distributions.

There is only 64-bit version of Imperium available.

Since the installer isn't digitally signed, the executable might be blocked by your web browser or Windows.

If your web browser blocks the download...

Dangerous download

...just unblock the file.

Now, after you have successfully downloaded the installer, run it. If Windows blocks the installation, choose More info → Run anyway.


After installation, just type "imperium" into start menu to launch it.

After you have downloaded the tar.gz file, extract it somewhere (for example: /home/me/apps/).

Next, run ./ in your terminal. This will register the shortcut for the application (it's all it does).

Now you should be able to launch the application by typing imperium into your OS menu (failing that, run it via ./imperium).

In the application, open the Command Palette, and type or pick "Open application folder". From that location, open the vmoptions.cfg file with a text editor. Add a line:, and replace the XXX with the percentage you want the UI to be scaled to (e.g. 150%).

On Linux, use glass.gtk.uiScale=XXX% instead.

You need to restart the application for this to take effect.

Imperium is written in Kotlin, and uses the JavaFX GUI framework.

The plan is to keep Imperium simple, and focus on usability of basic tasks.

Keep in mind that this is more of an experimental project tuned for my tastes and needs, than a professional product.

Also, I'm doing this alone, and I'm more of a designer than a programmer.

That said, I'm mostly interested in usability improvement ideas, and bug reports.

I don't own a Mac. Maybe someday in distant future.

No, and I have no plans to make it so.
