Host machine running out of disk because of Workstation

Hello,

I've an urgent problem. I've a CentOS 7 hosted on a Windows 10 machine.

My Windows is running out of space (4GB left out of 237). This is due to my VM getting bigger and bigger every week. It's present size is 188GB. When I look into my CentOS 7, the disk usage is 24GB. How is it then possible that my VM is so big? I try to use the "Shrink" tool from vmware-toolbox-cmd but it failed because my host machine hasn't enough space left.

Do you guys have a solution for me?

Thanks for reading!
