What is a VMX file?
A VMX file is a configuration file used by VMware virtualization software such as VMware Workstation and VMware Fusion. It stores settings for a virtual machine created using VMWare's New Virtual Machine Wizard. Each VMX file includes a virtual machine's memory, hard disk, and processor limit settings.
VMX files are paired with and used to load the virtual disk saved in a .VMDK file. They are saved in a plain text format and contain a list of settings in the form of property = value. For example, the setting for a VM's memory limit may be memsize = "512", which means that 512MB of RAM is the maximum memory allowed for that VM.
VMX files saved for VMware Fusion are generally stored within a .VMWAREVM package.
NOTE: If your created a virtual machine an earlier Linux version of VMware Workstation, that machine's configuration file may use the .CFG extension.
How to open a VMX file
For the most part, VMX files are not meant to be opened. However, if you need to manually edit a virtual machine's settings, you can open and edit that machine's VMX file in any text editor. For more detailed instructions, refer to VMWare's official documentation.
