Maximum File Size/# of Slides for a Presentation Apr 22, 2015 By Carrie F I have a project that is going to be translated into 23 languages. The client has requested that all the languages be in one course (it will be branching based on their language selection). The course is currently 35 MB and 65 slides long. Once it is translated and compiled, I am looking at around an 800 MB file with about 1500 slides. I am concerned that a file this size will cease to function or at least have bugs and glitches that I can't anticipate. Anyone else have a project of this size? Thank you!
