Powerpoint converts to "read only" and bad things happen...

Some pptx file I open suddenly say "read only" at the top.

  1. The file attribute in properties is not read-only
  2. The directory is not read-only
  3. When I save-as to a new file, then re-save as the original file it blows out my mp4 videos that I have embedded. The screen image is there but it shows up blank when I try to preview the page.
  4. I also seem to remember experiencing audio problems with the audio timeline in the past... but the big issue right now is the mp4 videos.

Why is this suddenly making my pptx file read only?

Hi Jim!

Are you working with local project files for your presentation? That's the only thing that comes to mind, right off the bat.

  • Work on your local drive (your C: drive). Working on a network drive or a USB drive can cause erratic behavior, including file corruption, loss of audio, and other unexpected behavior.
  • You should also make sure the directory path to your project files and your published output is less than 260 characters (for example C:\Articulate).
  • Avoid using special characters, accents or symbols in your file names (this includes spaces and underscores).

Additional information regarding "Naming Files, Paths, and Namespaces" in Windows operating systems can be found in the following Microsoft article.

I am following up with some team members to see if they have seen/assisted with issues like this. I have only seen one instance of this in the forums, and the user did not follow-up.

In addition, you may want to take a look at this article and see if this assists you.

In the meantime, if this is only happening to the one file, I'd recommend re-using the slides in a new file.

  1. Open a blank presentation in PowerPoint.
  2. Save the presentation.
  3. Click the Home tab.
  4. Click the drop-down arrow beside New Slide and select Reuse Slides.
  5. Click the Browse button and select Browse File.
  6. Locate your original PowerPoint file and click the Open button.
  7. At the bottom of the Reuse Slides panel, select the Keep source formatting check box.
  8. Right click the first slide in the Reuse Slides panel and select Insert All Slides.
  9. Save the new presentation and republish.

Note: Resources, such as audio and video, that you inserted via Articulate Presenter into the original presentation will need to be inserted again into the new presentation. You may need to export the narration from your original presentation. Then import it into the new presentation.
