My friend and I recently got into a conversation about unnecessary files, temporary files, and cache that should be deleted. We also talked about how there’s always a lack of free space on a Mac, and the laptop starts running slower. Turns out my friend has tons of apps and tools to delete this, delete that, find unnecessary files, and locate duplicate files. I was honestly shocked. The most I’ve ever done was move a file to the trash and then delete it from there.
