In order to merge split vmdk files into one, you need to use the vmware-vdiskmanager command. However, this is only available if you have VMware Fusion or VMware Workstation installed. VMware Player doesn’t have this.
A little utility can be downloaded separately from the VMware site (KB Article 1023856). you can download vdiskmanager-windows-7.0.1.exe.zip as attachment file .
Once downloaded, unzip and rename 1023856-vdiskmanager-windows-7.0.1.exe into vmware-vdiskmanager.exe and copy or move to the directory where VMware Player is installed.
The installation directory path may be look like as
C:\Program Files (x86)\VMware\VMware Player
In order to merge vmdk files, open a Command Prompt and CD to the directory where the vmdk files are located.
Assume you have the following vmdk files :
vmdkname.vmdk vmdkname-s001.vmdk vmdkname-s002.vmdk vmdkname-s003.vmdk .......
To Merge then into single vmdk file. open the command prompt and run the following command
"C:\Program Files (x86)\VMware\VMware Player\vmware-vdiskmanager.exe" -r "d:\VMLinux\vmdkname.vmdk" -t 0 MyNewImage.vmdk
The new vmdk file will then be created:
Creating disk 'MyNewImage.vmdk' Convert: 80% done.
Once done, move the original vmdk files to a different directory. Finally rename MyNewImage.vmdk to vmdkname.vmdk as it was originally named.
