Low on Disk Space / Not Enough Memory

If you are running low on your C: drive disk space and possibly getting a message that states that you don't have enough memory to save your project, try deleting all the files (not currently in use) in the folder %appdata%\Articulate\Storyline

 That location stores the recovery file for a Storyline project in case the app crashes. I was able to free 156 GB of space.
