.ppt is Microsoft 2003 or earlier word file while .pptx is 2007 and up.
.pptx
The full form of PPTX is "PowerPoint Presentation XML." It is a file format used by Microsoft PowerPoint for creating and saving presentations. The PPTX format is based on XML and is part of the Office Open XML standard, allowing for better data management and compatibility across different software.
.pptx
It could be either PowerPoint 2007 or 2010.
No, Office 2003 does not save files in the PPTX format, as this format was introduced with Microsoft Office 2007. Instead, Office 2003 saves presentation files in the older PPT format. Users who need to work with PPTX files can convert their PPT files using later versions of PowerPoint or online conversion tools.
The earlier extension in power point was PPT. The newer extension is PPTX in power point.
The DOCX file extension is a Microsoft Office Word document. The"X" at the end of these extensions all stand for the XML (Extensible Markup Language) format. The DOC file is similar but without the XML formatting. The PPTX and PPT are MS Power Point Presentation files. The XLSX and XLS extensions are MS Excel files. Even if you don't have Microsoft Office, you can download Open Office for free and view most, if not ALL, of these file types. I hope this has answered your question adequately. Best wishes!
In Microsoft Office 2007 and 2010, the extension is .pptx, whereas in earlier versions it was .ppt.
I believe the default is .pptx (The old default used to be .ppt)
