The name of the lfc server can be found out by:

> lcg-infosites  --vo your_vo  lfc (The lcg-infosites command is also useful for finding out other information. We refer to its man page.)

> lfc-mkdir /grid/hungrid/user_name/some_directory (All logical file names begin with /grid/virtual_organization. If you are a new user, the directory /grid/virtual_organization/user_name will not exist initially: you have to create it first, if you want an own directory.)

A list of Storage Elements may be obtained by:
