(Link) Convert a VMware hard drive image between single-file and split modes

http://mikebeach.org/2011/05/convert-a-vmware-hard-drive-image-between-single-file-and-split-modes/

To convert a single file to a split-file hard drive:

vmware-vdiskmanager -r <InDisk.vmdk> -t <type> <OutDisk.vmdk>

Type is one of:

• 0 : single growable virtual disk
• 1 : growable virtual disk split in 2GB files
• 2 : preallocated virtual disk
• 3 : preallocated virtual disk split in 2GB files

Example:

vmware-vdiskmanager -r winxp.vmdk -t 1 winxp-2.vmdk

Successful conversion gives the following output:

Creating disk 'winxp-2.vmdk'
Convert: 100% done.
Virtual disk conversion successful.
