Mass export to JPG (FileConverter.gms)

I need to export hundreds of .cdr files to .jpg. Have been reading these forums and it sounds like File Converter (FileConverter.gms) is what I need?

It's £14.99 in the extensions though - is it worth the £££?! 

Is there a cheaper/free way of easily doing it?

I'm very much a macro 'amateur' - I tried recording a temporary macro whereby I exported the file to .jpg, then closed the file. Figured that would save a little time compared to exporting each file manually. Doesn't work though (told you I was an amateur!).

Thanks in advance!
