    <p>You can use <a href="https://metacpan.org/pod/perlfunc#readdir-DIRHANDLE" rel="nofollow noreferrer">readdir</a> or <a href="https://metacpan.org/pod/perlfunc#glob-EXPR" rel="nofollow noreferrer">glob</a>.</p> <p>Or, you can use a module such as <a href="https://metacpan.org/pod/Path::Class::Dir#list-dir-children" rel="nofollow noreferrer">Path::Class</a>:</p> <blockquote> <p>Ordinarily <code>children()</code> will not include the self and parent entries . and .. (or their equivalents on non-Unix systems), because that's like I'm-my-own-grandpa business. If you do want all directory entries including these special ones, pass a true value for the all parameter:</p> <pre><code>@c = $dir-&gt;children(); # Just the children @c = $dir-&gt;children(all =&gt; 1); # All entries </code></pre> <p>In addition, there's a no_hidden parameter that will exclude all normally "hidden" entries - on Unix this means excluding all entries that begin with a dot (<code>.</code>):</p> </blockquote> <pre><code>@c = $dir-&gt;children(no_hidden =&gt; 1); # Just normally-visible entries </code></pre> <p>Or, <a href="https://metacpan.org/pod/Path::Tiny#children" rel="nofollow noreferrer">Path::Tiny</a>:</p> <blockquote> <pre><code>@paths = path("/tmp")-&gt;children; @paths = path("/tmp")-&gt;children( qr/\.txt$/ ); </code></pre> <p>Returns a list of <code>Path::Tiny</code> objects for all files and directories within a directory. Excludes <code>"."</code> and <code>".."</code> automatically.</p> <p>If an optional <code>qr//</code> argument is provided, it only returns objects for child names that match the given regular expression. Only the base name is used for matching:</p> </blockquote> <pre><code>@paths = path("/tmp")-&gt;children( qr/^foo/ ); # matches children like the glob foo* </code></pre> <p>Getting the list of directory entries into an array wastes some memory (as opposed to getting one file name at a time), but with only a few hundred files, this is unlikely to be an issue.</p> <p><code>Path::Class</code> is portable to operating systems other than *nix and Windows. On the other hand, AFAIK, its instances use more memory than do <code>Path::Tiny</code> instances.</p> <p>If memory is an issue, you are better off using <code>readdir</code> in a <code>while</code> loop.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
