On ESX/ESXi hosts, virtual machine disk (VMDK) files are located under one of the /vmfs/volumes, perhaps on shared storage. Storage volumes are visible from the vSphere Client, in the inventory for hosts and clusters. Typical names are
datastore1 and
datastore2. To see a VMDK file, click
Summary > Resources > Datastore, right-click
Browse Datastore, and select a virtual machine.
On Workstation, VMDK files are stored in the same directory with virtual machine configuration (VMX) files. On Linux this directory could be anywhere, and is usually documented as
/path/to/disk. On Windows this directory is likely to be
C:\My Documents\My Virtual Machines, under the virtual machine name.
