I have a DELL R710 with ESXI 5.0. I've created a VM with 100GB thin provision. I deleted most of the data. Is it possible to shrink the VM folder on the ESXI? thanks! Dotan.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Use Storage vMotion to move it to another datastore as a thick eager zeroed VMDK then move it back to the original location as a thin one.

what if I'm working with free ESXI 5 (no vmoition) with only one Datastore? – edotan Aug 1 '13 at 11:30
You could probably use Converter, drop it to a new file then reimport it? Never tried it to be honest. – Chopper3 Aug 1 '13 at 12:14

This answer explains how to do it

If you use a compressed filesystem eg. ZFS or thin provisioning over nfs then zeroing the blocks can be enough
