What is the extension ".qpcsv"? How do I use the SharePoint Essentials Lite Client?

The extension .qpcsv is used with the free 'ClickOnce' application "SharePoint Essentials Lite Client". This is a free tool that can be used by organizations who own the SharePoint Essentials Toolkit (or one of its components).
The "SharePoint Essentials Lite Client" is to be used under your license agreement (EULA) for the "SharePoint Essentials Toolkit".

You may download the "SharePoint Essentials Lite Client" tool separately here. Otherwise, it is included in the "SharePoint Essentials Toolkit" trial download.

The ".qpcsv" extension is a proprietary extension to be used only with this application. Its purpose is to allow end users who do not have the full SharePoint Essentials Toolkit application installed, to view and sort, group, filter and export reports generated by the "SharePoint Essentials Toolkit".

The application also supports automatic updates - users will be prompted to install updates automatically. If you need to turn off automatic updates for this application, please contact us.
