Sharing a ZIP file vs MP3 vs RPP file
This video explains why when trying to share your Reaper DAW creation with a teacher, friend, or colleague you can't just send them the small .RPP file as they will not be able to hear anything with that single file. I explain two options for sharing with me, the teacher:
1. Make a .ZIP file of the whole folder containing your Reaper file (.RPP) and all the MP3, WAV, or movie files it makes use of.
2. Render the Reaper session as an MP3 file and also take a screenshot so the teacher has a visual reference when making comments on what you've done.
