I'm looking for the software that allows attaching virtual storage much like
diskpart attach vdisk, but unlike the
*.vhd format supports splitting the image file into relatively small image files of the size 10Mb and less.
This is needed so that regular users can efficiently store and sync such file sets on a cloud storage.
Performance drop is not a problem.
vmware-mount.exe and a parent vmdk with 5x 20Mb vmdk extents. It mounts fine, but vmware sets a certain byte in the header of all extent files during mount which makes it unsuitable.
