To share data between members of the same project, you can use the common disk spaces $ALL_CCFRWORK, $ALL_CCFRSTORE and $ALL_CCFRSCRATCH which are accessible to all members of the project and attached to various disk spaces.

You can manage the access to your data simply by setting the unix rights on the sub-directories and the files according to the type of access wanted (read, write or read/write) via the unix command chmod.
