|---|
| 12 | The \fBmmcrfileset\fR command constructs a new fileset with the |
|---|
| 13 | specified name. The new fileset is empty except for a root directory, |
|---|
| 14 | and does not appear in the directory name space until the |
|---|
| 15 | \fBmmlinkfileset\fR command is |
|---|
| 16 | issued. The \fBmmcrfileset\fR command is separate from the |
|---|
| 17 | \fBmmlinkfileset\fR command to allow |
|---|
| 18 | the administrator to establish policies and quotas on the fileset before it is |
|---|
| 19 | linked into the name space. |
