NexusFile

Solid capability-wise, but unfortunately crippled by a garish interface and poor system integration.

I have to agree to disagree with fotzenlecker, I actually really like this program, the themes are dark, but that is one of the things I like about it.
I don't have the same problems, it runs VERY fast when I used it. However I do REALLY like this, it does have a few issues, and definitely needs SOME rework.
For instance I can't seem to do anything that would need admin privileges without starting up the program with admin privileges, it needs the ability, like explorer++, to ask for admin privileges when you do something like delete a file in program files without starting up the whole program with admin privileges and then going to the folder again.

Some other issues are you can't set it as your default file manager (I like to completely replace windows explorer), and you can't open a folder with it, if you do, it just opens up the default folder, so say if you click on my documents on your desktop and have it open as nexusfile, it doesn't open nexusfile in you documents, it just opens whatever nexusfiles default page is.

Horrible, sluggish interface. The menus are transparent and cannot be set opaque. When opening a menu, there's a delay in drawing the menu items. Renders the whole usability useless. Also, the design cannot be switched to anything else than black as for the inside of the window. You can only switch the color of the outer frames and borders. This software needs a lot of rework.
