Wordfast Classic is a CAT tool that works as a Microsoft Word add-in. As such, it cannot be used to translate directly other file formats than Word documents (DOCX, DOC, RTF). This video shows a “CAT hopping” (using one CAT tool to translate in another CAT tool) scenario in which Wordfast Pro 3 is used to extract translatable texts from a PowerPoint presentation, the texts are translated in Wordfast Classic and the translated texts are imported back into Wordfast Pro. Finally, Wordfast Pro is used to generate the translated version of the PowerPoint presentation. The same technique can be used to translate any file format supported by Wordfast Pro. The demo mode of Wordfast Pro 3 is sufficient for this purpose. Wordfast Pro 4 doesn’t currently support this workflow, as it can only export its bilingual documents to a Word table, and not reimport that table back into its own environment.
