What is a .VMX file?
A .VMX file is a type of configuration file used by VMware virtualization software, which includes programs like VMware Workstation and VMware Fusion. These files are important because they contain settings in plain text that define how a virtual machine should operate. This includes details about the virtual machine's memory, hard disk space, and processor limits.
When you use VMware software to create a virtual machine, it packages these settings in a .VMX file. This file is saved within a larger file package known as .VMWAREVM. Each virtual machine has its own .VMX file that is named after the virtual machine itself. For example, if you have a virtual machine named "Windows 11 x64," the corresponding .VMX file will be called "Windows 11 x64.vmx." You can open and edit .VMX files using any text editor because they are saved in a simple text format. The settings in the file are listed in a format where each setting is expressed as a property followed by an equals sign and its value. For instance, the memory limit might be set with a line like `memsize = "512"`, which means the virtual machine can use up to 512MB of RAM.
Programs that can open .VMX files include: - VMware Workstation - VMware Workstation Player - VMware Fusion - Any standard text editor (like Notepad in Windows, TextEdit in macOS, or Gedit in Linux) VMware Fusion is particularly useful for Mac users because it allows them to run operating systems like Windows or Linux on their macOS device. When setting up a new operating system through Fusion, it creates a virtual machine and the necessary configuration files, including the .VMX file and a virtual disk file (.VMDK).
If you need to access the contents of a .VMX file, you can locate it by right-clicking the .VMWAREVM package and selecting "Show Package Contents." This will reveal all the files related to that virtual machine, including its .VMX configuration file.
In summary, .VMX files are crucial for the proper functioning of virtual machines created with VMware software, storing essential configuration settings that help the virtual machine operate according to your specifications.
