I have increased size of a virtual machine, with machine --> edit (edit settings) -->

WHen I increase the size, it is increased.

ANd it came into unpartitioned space of the windows 10 machine, I increased that using disk management to 400 GB.

Later, I shrinked the partition and kept the 200 GB as unparititoned space.

Now, when I try to decrease the space in the esxi settings, I am getting below error.

SO, please suggest me how to decrease the disk space.

Even, I tried by connecting to ssh to the esxi server and ran the below command to decrease disk size.

vmkfstools -X <new size> <virtual disk>.vmdk

But getting error as not a valid vmdk file.

Please suggest.

Same error with any machine.
