As you will see later you can store the primary keys of selected records into extract files which will be catalogued for later use and further manipulation and selection.

The following dialogue displays previously saved extract files and the number of entries in that file.

The selection criteria that produced the selected extract file is shown in the lower part of the dialogue.

You are able to select an extract file for further manipulation by marking the relevant extract file entry and clicking OK.

Cancel returns to the previous screen.

Delete removes the entry and removes the physical extract file from the hard disk.

Merge allows you to mark more than one extract file and to combine them to produce a consolidated extract file. This de-dupes at the same time since an extract file contains the unique key of the currently opened file. When merging into a new file, this unique key will occur only once.

Name allows you to rename the extract file entry.

This displays the current Master file and the current record count based on the currently applied selection criteria.
