File Extensions in PowerPoint 2007
The default file extension introduced with PowerPoint 2007 is .pptx.
This extension signifies a presentation file saved in the Office Open XML (OOXML) format.
.ppt: This was the default file extension for PowerPoint presentations created in versions 2003 and earlier (the older binary format). PowerPoint 2007 can save in this format for backward compatibility, but it is not the default.
.ppx: This is not a standard PowerPoint file extension.
.pptm: This extension is used for a PowerPoint presentation that contains macros (VBA code). It is also part of the XML format, but only used when macros are present.
