Verifying that WSL2 file system has been moved to a different location

I followed this link to move my WSL2 file system from 1 drive to another. How do I verify that this did suceed?

I tried creating a pretty large dummy file in my root folder

pwd
>>> /home/vishal/
mkdir some_folder
cd some_folder
fallocate -l 50G dummy_img.img

But it doesn’t seem to increase the usage in both my C drive (where WSL2 is by default installed) or my D drive (where I moved it)

C:UsersVishalAppDataLocalPackagesCanonicalGroupLimited.Ubuntu_79rhkp1fndgsc which to my understanding is the image of WSL2 also seems to exist even after the move. Can I delete this file?
