How to use a custom background in Files

There are a number of ways to personalize Files, today we’re going to look at using a custom background.

1. The first step is to navigate to the themes folder. The easiest way to locate this folder is by opening the settings dialog in Files, clicking the information icon by the custom themes section and clicking on the “Open themes folder” button.
2. Create a new file with the xaml extension and place this template in the file.

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:BelowWindows10version1809="http://schemas.microsoft.com/winfx/2006/xaml/presentation?IsApiContractNotPresent(Windows.Foundation.UniversalApiContract, 7)"
    xmlns:Windows10version1809="http://schemas.microsoft.com/winfx/2006/xaml/presentation?IsApiContractPresent(Windows.Foundation.UniversalApiContract, 7)">
    <ResourceDictionary.ThemeDictionaries>
        <ResourceDictionary x:Key="Default">
            <ImageBrush x:Key="RootBackgroundBrush" Stretch="UniformToFill" Opacity="1" ImageSource="" />
        </ResourceDictionary>
        <ResourceDictionary x:Key="Light">
            <ImageBrush x:Key="RootBackgroundBrush" Stretch="UniformToFill" Opacity="1" ImageSource="" />
        </ResourceDictionary>
    </ResourceDictionary.ThemeDictionaries>
</ResourceDictionary>

3. Copy the background image or gif to the themes directory and set the ImageSource value to the files path.
4. You’re good to go!
