VPS & Dedicated Hosting: WHM Skeleton Directory
In WHM, this page tells you the location of the folder where you can place files for your clients.
Any files in the skeleton directory will automatically be uploaded to each new cPanel you create. The files will not appear in cPanels which were already created.
This is useful if you want all new cPanel accounts to have a default.html file, or want to preinstall a PHP script on every new cPanel or want a standard .htaccess file across new accounts. Resellers (customers reselling hosting) frequently use this feature to create a default page (usually default.html) that welcomes their clients and serves as a "parking" page until the resold customer upload's their own content.
