I had around 44 GB left on my hard drive. I have a Mac OS X Lion. ScreenFlow 4.0.5
I played a game called minecraft and recorded it with screenflow. I made around 3 videos of 8-11 minutes. I didn't like neither of the videos so I deleted them right after I finished recording it!
I then checked Activity monitor and see that I have 24 GB left! I downloaded OmniDiskSweeper and Disk Inventory X to check where that 20 GB went but there's nothing I could find related to ScreenFlow.
This is so weird because I didn't save anything, I deleted the videos right away and somehow I lost that much space?! All I did is record 8-11 minutes of Minecraft.
And I checked if there were any.SCC files with Easy Find and I couldnt find any!
