This message occurs when purging data from within one of the unused data reports, and informs you of the number of data sets and data elements that are about to be purged/deleted.
Note that, in the case of the holidays sets and Saras unused reports, the displayed number of sets and data elements is an estimate, if you did not select all of the displayed unused data. The reason is that you may have selected a folder, but not one of its sub-folders, in which case the nonempty folder will not be deleted, and the confirmation dialog that appears after the purge, will contain a reduced number of deleted sets and data elements.
