COPY TO MyTempFile CDX

And then switching the file names.

>When I attempt to pack a file which has been in use in an application for some time, I get an error 41, fpt file deleted, missing, or cannot be found. The .fpt file is in the default directory. In fact, if I bowse the file I can double click and see the contents of the memo fields. None the less, I get this error message. Can anyone help?
