What is an NVRAM file?

NVRAM files mostly belong to VMware Workstation by VMware. NVRAM is a file that stores the state of a virtual machine's (VM's) BIOS.

Usage: These files, along with others, are automatically created when a new VM is created using a VM creation software. They are binary files too, thus, they are not meant to be edited or manually used. It is possible to open them using VM software, if necessary, but it should be avoided if possible. Most possible errors with the file can be fixed by just deleting the file and letting the VM create it again upon the next boot.
