Appearance

The Appearance page in settings allows you to personalize your Files experience with a variety of aesthetic options. For those who love to tinker, we’ll even show you how to manually adjust the settings file for additional background colors and fonts.

Theme customization

Toggle effortlessly between dark and light mode to match your style or ambient lighting. The “Default” setting syncs with your Windows system theme, ensuring a cohesive visual experience.

Transparency effects

Choose your preferred backdrop material to add a layer of transparency to your window background. Opt for Mica Alt for a subtle effect (note: Mica requires Windows 11) or Acrylic for a frosted appearance. To fully appreciate these effects, ensure your background color is set to transparent.

Background color

Personalize the background color of your window from a spectrum of pre-selected shades. For a unique touch, use the color picker to input a custom color or adjust transparency to your liking.
