<H1>u (Update) command</H1>
<P>Update older files in the archive and add files that are not already in the archive.</P>
<P>Note: the updating of solid .7z archives can be slow, since it
can require some recompression.</P>
<H4>Example</H4>
<PRE class="example">
7z u archive.zip *.doc
</PRE>
<P>updates <SPAN class="filename">*.doc</SPAN> files to archive
<SPAN class="filename">archive.zip</SPAN>.</P>
<H4>Notes</H4>
<P>7-Zip doesn't use the system wildcard parser. 7-Zip doesn't
follow the archaic rule by which *.* means any file. 7-Zip treats
*.* as matching the name of any file that has an extension. To process
all files, you must use a * wildcard.</P>
