A switch has been added to ctutil to implement conversion from Btrieve's DDF files into c-tree XDD files, which contain schema information about the data and index structures. The format is as follows:
ctutil -ddf2xdd <dirname>
Where <dirname> is the name of a directory that contains file.sav, field.sav, and index.sav files.
In the same directory, it creates one XDD file for each file contained in file.sav. These three files should be generated starting from file.ddf, field.ddf, index.dff using the btutil command as follows:
butil -save FILE.DDF file.sav
butil -save FIELD.DDF field.sav
butil -save INDEX.DDF index.sav
