Abstract
A system, method and computer program product for sharing files among users of multiple Virtual Environments (VEs). Each VE user has private objects, such as files or directories, that contain links to selected shareable files or directories in a common memory storage area. Each VE user also has a private file area to store files. If a VE user wishes to access a shareable file to perform an action that does not modify the shareable file, then the VE user private file allows the VE user to access the sharable file in a common memory storage area. The VE user private file contains a metadata attribute specifying the link to the shareable file. If the VE user wishes to access a shareable file and perform an operation that modifies the shareable file, the system makes a copy of the shareable file and places the copy in the VE user's private file area.
