You do a good job of PPT after closing the PPT there is no prompt to say? "File"...." Has been modified and you wish to update it in the zip file?"
I think you didn't click "yes" so it wasn't saved in the zip
You have to open the zip first? see? What is the name of the ppt template file in there
Then double click to open my computer? Click on Search? Type in the ppt template file name? Click Search Now? Should be able to search out the location of this good PPT (provided that you have saved ah after you do) do not understand then hi me or ask, right? I hope to help you!
