The project size is growing exponentially

So i am doing a full blueprint project. What worries me is that the size is increasing exponentially lately. is this normal?. My logs folder is about 3.8 gb. The full project is about 5gb. Why is this happening? can i delete these logs or something ? what to do?

The folder is project/saved/logs.

Pretty much everything in the saved and intermediate folders can be deleted.

Thank you.
