Purchase Document Library Explorer - Step 1
A Server License allows you to user Document Library Explorer with up to five different
host names. This is ideal for scenarios in which your SharePoint installation may
have different urls for intranet, extranet and internet access. It also means you
can use the same license with a UAT or development environment.
If you need more than five host names, either multiple server licenses or an Enterprise
licence may be purchased. An enterprise license can be used with as many host names
as you like.
