# FileCache.config

> The **~/Configuration/FileCache.config** file allows you to configure the cache of Customer's Canvas.

The following snippet shows parameters of the Customer's Canvas cache, which you can set up in either the `Aurigma.DesignAtoms.FileCacheConfiguration` section of **Web.config** or the separate **~/Configuration/FileCache.config** file, with their default values.

```xml
<Aurigma.DesignAtoms.FileCacheConfiguration>
    <add key="MaxSize" value="4294967296" />
    <add key="CleanUpInterval" value="1800" />
    <add key="MaxUtilizationThreshold" value="95" />
    <add key="UtilizationTarget" value="70" />
    <add key="RootPath" value="~/App_Data/FileCache" />
</Aurigma.DesignAtoms.FileCacheConfiguration>
```

Let's look at these parameters in more detail.

Name | Description | Possible values

MaxSize | The maximum size of the cache, in bytes. The default value is <code>4294967296</code> (4GB). | number

CleanUpInterval | The interval between cleanup runs, in seconds. The default value is <code>1800</code> (30 minutes). | number

MaxUtilizationThreshold | The maximum cache utilization level (in percent) that triggers automatic cleanup. When the cache size reaches <code>MaxUtilizationThreshold</code>, the cleanup process starts. The default value is <code>95</code>. | number

UtilizationTarget | The utilization level (in percent) to which the cache should be cleaned up. When the cleanup algorithm reaches the <code>UtilizationTarget</code> level, the cleanup process stops. The default value is <code>70</code>. | number

RootPath | The folder path where the cache is stored. The default value is <code>~/App_Data/FileCache</code>. | folder path
