Apple software

Hi,

I have a very important file that was created from an apple mac software. It’s some of of presentation but I’m unable to open it with powerpoint for mac. Can someone show me how to find out what application was used to create this file?

I was able to open the file up on a pc and then use notepad to open it up. It appears that the file was created in 1996. The file is titled “Presentation.” I’m able to see the written content but unable to see the images because they are showing up as symbols. Can someone please help me on this because it’s really important for my boss to see the images on this file? Thanks!
