Here’s something new (to me anyway).
I was sent PowerPoint that was slow to open, and slow to print. It was 6MB. Too big considering the content but it still should have opened faster.
I had a look and found that many of the text boxes were in fact embedded docs
(R. click on the text box and you’ll see a Document Object option).
So I decided to check the file by clicking File>Info
Then selected Check for Issues then Inspect Document.
Document Properties was highlighted so I clicked Remove all and Close.
Hey Presto!
6MB turned into 1MB and it was fast to open an print.
