Hi Oriol,

Use and INCLUDETEXT field.

Please post any further questions or followup to the newsgroups for the

Hi Oriol

Another option is to store as an AutoText in the document template and use
an AUTOTEXT field. Note that both this and the INCLUDETEXT method require
fields to be updated before any change is seen in the document.

Or you could look at inserting the text file as a linked object. This can be
made to update automatically on document open, but the formatting and
editing implications are different from the INCLUDETEXT field.
