Working with
groups of files

Wildcards

It is sometimes useful to refer to a group of files or directories in
one command. You can do this by using wildcards — symbols that
refer to any character or set of characters in a filename. The two
wildcard symbols are # and *:
■ # stands for any character
■ * stands for any string of characters.
EXAMPLES
AB# can refer to ABC and ABZ; it will also match
AB, but not ABCD
* can refer to any file or directory in the
currently selected directory
ONE.W* refers to all the files and directories in the directory
ONE that start with W, including a file or directory
called W
When you use a wildcard to refer to a group of files, the
reference you give — AB#, for example — is called an
ambiguous reference.

Protecting groups of files

You can use ambiguous references with *ACCESS to set access
strings for more than one file.
Type: *ACCESS <reference><access>[RETURN]
<reference> here stands for ambiguous file reference;
<access> stands for access string.
EXAMPLES
*ACCESS A### R/R
will give the access string R/R to all your files that start with
an A and are up to four characters long.
*ACCESS
