DDF file

DDF file

I have a file B.BTR that shows in the file folder. There is no reference for this file in any DDF. Is there a way I can access this file and How should I do it.
I know the kind of info I should find here, but I do not know the way to access it.
Thanks in advance.

RE: DDF file

Is this from a third party application?  If so, contact the vendor and get updated DDFs that describe all of the data files.  
If it's a custom app and you know the exact record structure, then you can define the table structure for DDFs.
You can do this a number of ways including a "CREATE TABLE" SQL statement through the PCC (or other ODBC enabled application), The Create Table Wizard, or a third party DDF Builder.  Which method you use will depend on the version of PSQL you are using and also your comfort level (I prefer SQL statements over a DDF Builder but others prefer to avoid SQL statements).

RE: DDF file

This file was added at one time in by a third party  apps. The last date is pretty old, and I can ask the vendor since this file do not show in the ddf I have.
I will create a SQL to create the table, as DDF are something I am not very familiar, just know they are her.

RE: DDF file

If you need to analzye the structure you can take a look at BtSearch32 at www.nssdd.com.  There is also a video of creating a DDF file on the support button.
