If a shared folder is not created by the user who powers on the virtual machine, it is deactivated by default. This is a security precaution.
Folder sharing is also deactivated by default for Workstation 5.x virtual machines, regardless of who creates the folder.
Important: Enabling shared folders on all virtual machines can pose a security risk because a shared folder might enable existing programs inside the virtual machine to access the host file system without your knowledge.
