Is it any way to make virtual disk smaller (not shrink!)

[froff]

hello
I created virtual disk with declared size with is too big.
Now disk contains some data.
Is it any way to reduce declared disk size without losing data or changing disk uuid?
Reducing partition size is no problem, and after that whole disk size reduction should be technically possible.
Is it or no?

Dynamic or fixed?
How big is it now?
Why is it now too big?

hello
It's dynamic disk. 200GB. I would like to make it much smaller in order to make shrinking process faster and less space consuming.

Use CloneVDI. Than the size does not matter.
