When a print merge cannot be successfully completed in CorelDRAW  the error message most
commonly generated is "Wrong file format or could not open".

The example of performing a text merge was omitted from the CorelDRAW 4 manual, therefore,
Technical Support has prepared the following document to assist you in successfully merging
your text files.

Print Merge - Error: "Wrong file format or could not open."
This error will occur in any one of the following situations.

          The text file is not structured correctly.  For proper structuring of the text file refer to the
     CorelDRAW 4 manual. There are two models for structuring the text.

          The text is not saved in a text only format.   If the text file will not open in Notepad, it is
     not saved in the correct format.  Recreate this text file in Notepad, or save the text file as a
     text only file with the word processor it was created in.

          There are inconsistencies between the text strings that appear in the form drawing and the
     field names used in the text file. In the form drawing each string of text that is to be
     merged must be a separate artistic text string. 

          The field names in the text file must match exactly the text strings in the form drawing. If
     the text string in the form drawing is a mix of uppercase and lowercase than the field
     names in the text file must also be a mix of uppercase and lowercase. Ensure there are no
     extra spaces or carriage returns in the text strings of the form drawing.  To check this,
     click the text with the Pick tool, and click Edit, Edit Text.
