Configuration Manager version 1606 brings the ability to customize the cache folder size for the entire site using client settings. When the client is installed the restrictions are applied to the cache folder which is located at %windir%\ccmcache. The default size restriction for this folder is 5120MB.
Be careful when encrypting the file folders on the client. ConfigMgr cannot download content to a folder that is encrypted, and the resulting error for this particular problem makes it difficult to track down the source.
