You should be able to extract the information via ODBC if you get the latest drivers from Pervasive at www.pervasive.com/downloads. As long as you have your DDF files which are the file.ddf, field.ddf and index.ddf.
I've worked with Platinum since 1991 so I am familiar with the different structures of the files. I've written a number of applications that interface with the data files.
If you want to view the data you can download BtSearch at www.nssdd.com. It is another method of extracting the data to CSV format.
