Software Engineer
Microsoft PowerPoint provides a Fast Save option that allows speeding the save process by storing only the changes at the end of file. Thus the characters' logical order doesn't match with that of physical order. This contributes in increasing overall size of PowerPoint presentation to more than required. Also, it is among the top causes that is responsible for causing a PowerPoint PPT to get corrupt. Thus, turning off 'Allow fast saves' feature is always recommended to avoid such corruption or otherwise, it will require you to Recover PowerPoint.

Let's consider a PowerPoint user who has enabled 'Allow fast saves' feature. The user stores valuable data in his presentation, but when he/she tries to open the file, he gets the below error message:

“PowerPoint cannot open the type of file represented by filename.ppt”

This error indicates file corruption that might have resulted because, the 'Fast Save' option was enabled.

Description
'Allow fast saves' just appends the changes to end the file. So the result can be a quite larger file till the time you click 'Save As' to re-save the file. Saving the file includes making all the changes and re-writing all the data. This whole process creates fair chances for file to get corrupt.

Solution
The best option to avoid PowerPoint file corruption is to turn off the 'Allow fast saves' feature. For this, you need to go to 'Tools' menu, click the 'Options', and then click 'Save' tab. You can then clear check box of 'Allow fast saves' and turn off the feature.
