Vmware Station 自带的命令行工具"vmware-vdiskmanager"可以通过改变"磁盘类型Disk type"这一选项，将多个vmdk文件合并为一个或者将单个文件分为多个2G以内的文件。其帮助文档可以通过在DOS命令窗口输入E:\Program Files\VMware Workstation>vmware-vdiskmanager.exe来获取。

VMware Virtual Disk Manager - build 1744117.
<span style="background-color: rgb(255, 102, 102);">Usage: vmware-vdiskmanager.exe OPTIONS <disk-name> | <mount-point></span>
Offline disk manipulation utility
  Operations, only one may be specified at a time:
     -c                   : create disk.  Additional creation options must
                            be specified.  Only local virtual disks can be
                            created.
     -d                   : defragment the specified virtual disk. Only
                            local virtual disks may be defragmented.
     -k                   : shrink the specified virtual disk. Only local
                            virtual disks may be shrunk.
     -n <source-disk>     : rename the specified virtual disk; need to
                            specify destination disk-name. Only local virtual
                            disks may be renamed.
     -p                   : prepare the mounted virtual disk specified by
                            the mount point for shrinking.
     -r <source-disk>     : convert the specified disk; need to specify
                            destination disk-type.  For local destination disks
                            the disk type must be specified.
     -x <new-capacity>    : expand the disk to the specified capacity. Only
                            local virtual disks may be expanded.
     -R                   : check a sparse virtual disk for consistency and attempt
                            to repair any errors.
     -e                   : check for disk chain consistency.
     -D                   : make disk deletable.  This should only be used on disks
                            that have been copied from another product.

  Other Options:
     -q                   : do not log messages

  Additional options for create and convert:
     -a <adapter>         : (for use with -c only) adapter type
                            (ide, buslogic, lsilogic). Pass lsilogic for other adapter types.
     -s <size>            : capacity of the virtual disk
<span style="background-color: rgb(255, 102, 102);">     -t <disk-type>       : disk type id

  Disk types:
      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
      4                   : preallocated ESX-type virtual disk
      5                   : compressed disk optimized for streaming
      6                   : thin provisioned virtual disk - ESX 3.x and above</span>

     The capacity can be specified in sectors, KB, MB or GB.
     The acceptable ranges:
                           ide/scsi adapter : [1MB, 8192.0GB]
                           buslogic adapter : [1MB, 2040.0GB]
        ex 1: vmware-vdiskmanager.exe -c -s 850MB -a ide -t 0 myIdeDisk.vmdk
        ex 2: vmware-vdiskmanager.exe -d myDisk.vmdk
        ex 3: vmware-vdiskmanager.exe -r sourceDisk.vmdk -t 0 destinationDisk.vmdk
        ex 4: vmware-vdiskmanager.exe -x 36GB myDisk.vmdk
        ex 5: vmware-vdiskmanager.exe -n sourceName.vmdk destinationName.vmdk
        ex 6: vmware-vdiskmanager.exe -r sourceDisk.vmdk -t 4 -h esx-name.mycompany.com \
              -u username -f passwordfile "[storage1]/path/to/targetDisk.vmdk"
        ex 7: vmware-vdiskmanager.exe -k myDisk.vmdk
        ex 8: vmware-vdiskmanager.exe -p <mount-point>
              (A virtual disk first needs to be mounted at <mount-point>)

执行合并功能（D:\My Documents\My Virtual Machines\Ubuntu\为虚拟机安装路径）

vmware-vdiskmanager -r <原文件路径(含文件名)> -t 0 <合并后文件路径(含文件名)>

执行拆分功能：vmware-vdiskmanager -r <原文件路径(含文件名)> -t 1 <分割后文件路径(含文件名)>

D:\VMware_ones>vmware-vdiskmanager -r G:\ubuntu\Ubuntu.vmdk -t 1 G:\ubuntu\ubuntu2.vmdk
VixDiskLib: Invalid configuration file parameter. Failed to read configurationfile.（错误，不过好像是bug，不用理他）
