Convert all slides of a PowerPoint file, C:\PowerPoint\Semi.ppt, to a single DOC format file named C:\PPTOutput\SemiDOC.doc. Verbose mode invoked for on-screen confirmation. Use the following syntax:
ConvertPPT /S "C:\PowerPoint\Semi.ppt" /T "C:\PPTOutput\SemiDOC.doc" /C101 /V
Note it is highly encouraged that you use the Verbose (/V) switch initially to see what the status of your conversion is.
