Versions earlier than 3 of VMware Player were unable to create virtual machines (VMs), which had to be created by an application with the capability, or created manually by statements stored in a text file with extension ".vmx"; later versions can create VMs. The features of Workstation not available in Player are "developer-centric features such as Teams, multiple Snapshots and Clones, and Virtual Rights Management features for end-point security", and support by VMware. Player allows a complete virtual machine to be copied at any time by copying a directory; while not a fully featured snapshot facility, this allows a copy of a machine in a particular state to be stored, and reverted to later if desired. By default changes (including proxy settings, passwords, bookmarks, installed software and malware) made in a VM are saved when it is shut down, but the .vmx configuration file can easily be edited to autorevert on shutdown, so that all changes are discarded.
