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 Memsource Personal Edition 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 Memsource. Finally, Memsource is used to generate the translated version of the PowerPoint presentation. The same technique can be used to translate any file format supported by Memsource. The free version of Memsource (Personal Edition) is sufficient for this purpose, but it only allows processing of two files at a time.
