Convert vdi to qcow2

qemu-img convert -f vdi -O qcow2 Windows10.vdi Windows10.qcow2

Convert qcow2 to vmdk

qemu-img convert -f qcow2 -O vmdk originalfile.qcow2 convertedfile.vmdk

Delete snapshots

qemu-img snapshot -d snapshot1 debian.qcow2

Combine multiple vmdks to a single vmdk

C:\Program Files (x86)\VMware\VMware Workstation

C:\Program Files (x86)\VMware\VMware Workstation\vmware-vdiskmanager.exe -r vmdk-primary.vmdk -t 0 combinedImage.vmdk

The vmware-vdiskmanager.exe lives with VMWare Player (or your chosen VMWare product).

1. Once done, you will still have the original files.
2. You will have to rename the combinedImage.vmdk file to the original file name vmdk-primary.vmdk.
3. Once you are happy with the new image, you can delete the old files, just make sure it works first.
4. Note that the file you specify is the one with the original filename without the suffix -0001 etc.
