OFC.EXE to convert DOT to DOTX file for Office 2007 upgrade

Question

 I need to mass convert a folder of 1700+ word templates (.dot) plus a few .xlt files .  I am using the command line OFC.exe from the Office Migration Planning manager install but I get the following error for the .dot files:

Error: Unknown file type: c:\tempdocs\temp.dot

This is the error repeated for each dot file.  The .xlt files convert ok.  It's just the .dot with the error.  Also, if I save the dot as a doc, the .doc will convert without errors?

Anybody seen this before?

Answer 1

Solved issue by writing an application to open and save the dot/xlt templates to dotm/dotx and xltm/xltx files.

Answer 2

Can you post your application here?  I am looking to do the same....convert many .dot files to .dotx.
