PowerPoint presentations can arrive in different file formats:
- PPT is the default file extension for saving presentations in PowerPoint 2003 and earlier versions.
- PPTX is the default file extension for saving presentations in PowerPoint 2007 and later versions.
- PPS is the the show mode extension in PowerPoint 2003 and earlier -- these files run in "play-presentation" mode when double-clicked.
- PPSX does the same thing in PowerPoint 2007 and later -- it runs in "play-presentation" mode when double-clicked.
For editing a PPSX file, instead of double clicking on it, as it would start the "play-presentation" mode, open PowerPoint and then open the file:
Still, if the PPSX file is password-protected, you have to enter the correct password to unlock it and be able to alter the contents and paste them in other presentations:
Actually we can open password-protected PowerPoint PPSX presentations without knowing the password. In explorer, rename the presentation, changing the file extension from PPSX to ZIP:
Then open the ZIP file, and search for the presentation.xml file in the ppt folder:
Extract the presentation.xml file from the ZIP file, then open it in a text editor (here is Notepad++, but plain Notepad will do just as well)
Close to the end of the file, find the tag highlighted, starting with
mark it and then delete it, like this:
Save the file, then put it back into the ZIP file in the same position, replacing the unedited one:
Finally, rename the ZIP file back to the PPSX extension:
Done! Now open PowerPoint, and open the Pres.ppsx file:
Mission accomplished! All the contents of the presentation are now at your disposal.
