In fact, we can do it on the slide master to achieve this function.
First step: Open the PPT2003 file, first add the number to each slide (equivalent to the page number in Word). Click the menu "Insert"-> "Slide Number", select "Slide Number", and then click "Apply All".
Step two: Next look at the total number of pages in the entire PPT2003, for example, this PPT has 10 pages, and then we're going to go to the slide master status to edit the master. Click the menu "View"-> "master"-> "slide master" into the master state.
The third step: Watch the slide master, the master of the lower left corner of a "digital area" where, with a mouse click can be edited.
Move the cursor to the back of the "<#>" symbol, and then type "/10", of course, "/10" You can change it to the form you want, such as "10 pages" and so on.
Fourth step: After editing, click the menu "View"-> "normal", exit the master status, and save the entire file.
This allows us to see the total number of pages we have set on each page.
