Why do I have multiple VMDK for my VMWare Catalina setup?

I hope this is the right place for this; I couldn't find any other subs on reddit where to ask this (the vmware sub doesn't like macOS questions).

So I used a vmware disk image with catalina in it and set it up afterwards. Everything works fine; however, I set the initial hard-disk to be 100GB and now it takes 130GB. There are multiple .vmdk files in the virtual machine folder and they are connected, i.e. if I move one of them, vmware will ask for its location when trying to boot up.

​

Does anybody have any idea why this is happening? I don't have any large files in the virtual machine and most of the space if free so I don't understand why it's expanding.

Thank you!
