VMX

A VMX file is a backup of the previous version of a VMF file. It is created and replaced every time the VMF is saved.

Note: In some cases it may be necessary to roll back to the VMX file, simply delete or rename the VMF and then change the VMX extension to VMF.

Warning:VMX backup files are replaced every time the VMF is saved, which could be any time between 20 seconds ago and 20 minutes ago!

Tip:Enable autosaves. Using a version control software, such as  Git, is also highly recommended.
