Virtual machine files
Each VM consists of several types of files usually stored on the host operating system.
Here is a list and description of files that make up a virtual machine:
- Configuration file (<VM name>.vmx) – the primary configuration file that stores the settings of a virtual machine
- BIOS file (<VM name>.nvram) – a file that contains the virtual machine’s BIOS
- Log files (vmware.log or <VM name>.log) – a virtual machine log file
- Paging file (<VM name>.vmem) – the virtual machine paging file
- Disk file (<VM name>.vmdk) – virtual disk file that stores the contents of the virtual machine hard disk.
- Snapshot data file (<VM name>.vmsd) – a file that stores information and metadata about snapshots
- Snapshot state file (<VM name>.vmsn) – a file that stores the running state of a virtual machine at the time you take the snapshot
- Suspend state file (<VM name>.vmss) – a file that stores the state of a suspended virtual machine.
