How to view broken powerpoint pptx?

I worked on the presentation Powerpoint, after successful completion of 4 hours of work and close the file, save the presentation as the format pptx. On the next day at the opening-message that the file content that can not be read. And even with the full confidence of the file access error. 

Hi,

Would you please provide the complete error message to us so that we can narrow the issue down?

Does this error happen to other presentation files? If it only happens with the particular file, we can try the following steps to see if you can open it successfully:

1. Create a blank presentation file.

2. In the blank presentation file, under Home tab, click the New Slide drop-down list, and then click Reuse Slides.

3. In the Reuse Slides task pane, click Browse > Browse File. Click the damaged presentation, and then click Open.

4. Right-click one of the slides in the Reuse Slides task pane, and then click Insert All. 

If this operation is successful, all the slides from the damaged presentation, except the slide master, are inserted into the new presentation.
