After a selected number of items are exported to excel note that the column order in the .csv file is not the same as the column order in Pinker. Invariably the columns in the .CSV file are presented in this order:
Name;Path;Date modified;Size;Type;Duplicates;Hashcode;Pages

Pinkerfind team is working to eliminate this discrepancy and will inform the user community in due time. Please use Excel's functionalities to arrange them in the expected order.
