How do I purge the C:/Mac/MacDisk file?

Hello, I am currently trying out the trial version of Parallels Desktop and am experiencing a disk space issue.
My Mac is an M1 PRO with a 994 GB HDD, and I currently have over 200 GB of free space on the Mac's disk.
I installed Parallels Desktop and Windows 11 and tried several resource-intensive programs. I quickly realised that the 256 GB VM was too small. I wanted to increase the VM to 300 GB, but W11 remained at 256 GB.
I deleted a resource-intensive app to free up space, but the W11 C drive did not free up any space. In C:/Mac, Mac disk had a size of 190 GB.
I thought W11 was malfunctioning, so I deleted the W11 VM to create a new one, but I realised that the C directory had even less space. C:/Mac Mac disk increased to 216 GB, leaving me with even less space.
How do I purge this Mac disk? I don't understand how it works.
Thank you for your help.
 
Disclaimer: this method permanently removes some capabilities of the VM, especially the quick File/Application sharing between the host and VM. I'm not entirely sure if all the services in step 7 need to be deleted but it works on my machine and I'd rather have the extra drive space than the services I removed.

-First make sure the VM is off
-go to control center for the Windows 11 machine
-turn off everything in "Sharing" (both share Mac and share Windows) and "Appliactions"
-boot the VM and open File Explorer
-go to C:/Program Files/Parallels/Parallels Tools/Services
-Open a separate window with Task manager and search for Parallels
-kill all the running services except for Parallels coherence and then delete them in the file explorer before they automatically restart
-go into settings > system > storage
-delete the Mac folder and then reboot

Once you reboot the Mac folder should be gone. Saved me 150GB
