Rendering causes Disk to be full

Hi there!

Do you have an idea where I can delete all the files that are in the cache and other files that have been saved during the rendering process?

I have purged the cache, set my D:\\ drive HDD now as the cache saving location and removed the SSD as my render location. Anyways my disk (SSD) is still full from the rendering, which folder do I need to delete?

Thanks  a lot!
