Help With Pinnacle Studios 26

[Magnum Arts]

Here is my issue and I can't find an answer anywhere, not even with the Corel support chat line. Those people in India don't seem to know anything. When I go to export my project in Pinnacle Studio 26, there is a bar at the bottom that says "Used Space 84%." The program is crashing and getting very sluggish when exporting, so I need to free up some of that space, but for the life of me, I cannot figure out how.

• I have deleted my rendering files from my computer
• I have deleted unnecessary video and image assets from the program I'm not using, to free up space
• I have done a disc defragmentation
• I did find a file on my PC on the following path: (C: ) > AppData > Local > Pinnacle_Studio_26 > Studio > Scratch > RenderCache3. I deleted those files

I have looked everywhere to try to find where this space is being occupied, but I cannot figure it out. Does anyone have any idea what I can do to free up this space on this program? I just don't know where else to look
