I’m actually surprised this is supported for some configurations - thanks
for starting the thread. As for how others deal with this - e.g. VMware files
never shrink, but there is a „vacuuming“ function that compresses the
virtual disk while the VM is offline in the workstation products. For ESXi
I think the only way is to actually copy the image file to a new one with
vmkfstools.

Used to use defrag and sdelete a lot in Windows VMs in the past, then
ran the compaction …

Kind regards
Patrick
