App Data Temp Folder has Cubase .peak files?

Why would cubase make .peak files in my temp folder and not in the project folder? Can I safely delete all of the files in AppData/Local/Temp?

No clue. But I am curious why you would feel the need to delete part of a tiny little folder?

some peoples temp folders get to be 100GB in size. Mine is like 40GB, and my OS drive is a 256GB SSD, so im trying to pare it down. I was just surprised to see something cubase related in there.

I don’t know what the Cubase files you found are for but everything in your temp folder is supposed to be safe to delete. If you are concerned rename them instead of deleting. Once you are sure it’s ok then nuke them.
