The major difference is file format. MS office 2007 uses xml file format ie docx, xlsx, pptx, etc.
This is the new format used for Powerpoint presentations. I believe this format came in with MS Office 2007. It claims to have more options that .ppt, which is the old MS PowerPoint format.
.ppt for versions up to 2003 and .pptx from version 2007 onwards.
The 2007 versions of Microsoft Office suite introduced an XML file format, which actually has more than one file, but then all of these files are compressed, using the ZIP format, into a single file. The file extension has an X at the end. So while previous versions of PowerPoint had a .PPT extension, the new format has .PPTX extension, to denote the new format.
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!
Open it using MS Office 2007 or later or even OpenOffice.org supports this. Other options are LibreOffice, KOffice, etc. Online versions include Google Docs and Microsoft Office Live.
.ppt is Microsoft 2003 or earlier word file while .pptx is 2007 and up.
This is quite simple .ppt is Microsoft 2003 or earlier word file while .pptx is 2007 and up.
Up to Office 2003 the Word extension was .doc and Powerpoint was .ppt. From Office 2007 onwards Word is .docx and PowerPoint is .pptx so just add an x at the end of each.
Go to File/Open and browse where you saved your file at. Remember you should have saved (in OpenOffice) in a format that Microsoft can read. Word: .doc, docx Excel: .xls; xlsx, PowerPoint: .pps; ppt; pptx
The .PTX file extension is used as a Court Reporter Transcript file or as RAW file generated from a Pentax camera
Native files are the files created in the program you are in. You have the option to save your file in another format, but its best to save the file in native file if wanting to come back to edit your work. Usually, when you save as another file the quality will lack. For example when you use Photoshop (.psd) or Adobe Illustrator (.ai)or PowerPoint (.pptx). If you save the file in the incorrect format and try to access, you may not be able to view or edit.
