To delete all the lists held within a single Excel file container call the "Delete Lists of Patterns from a File source" dialog from the ACBA Tools menu - Audit Tools, List Analysis, Pattern Lists, Delete by Workbook.

This instruction generates the following user form, which lists the file containers holding the List Series registered to your copy of ACBA Tools.

You may select more than one file.
The system requires that at least one Excel file is left registered.
If you wish to delete all references to search criteria lists, select Delete All Pattern Lists.
