Filename was Truncated
To show the presentation at a later time, you need to locate the PowerPoint file. The original filename of my presentation was called Pack and Go. This file name has more than 8 characters and contains spaces, so therefore, it is an invalid filename.
When the file was unpacked, Windows truncated the name and renamed it to follow its naming conventions to PACKAN~1.PPT. You have probably seen instances of other filenames such as this in the past. This is the reason why that happened.
