A hardlink entry in a .7z&lt;br /&gt;
file would mean something like "create a hardlink if supported and&lt;br /&gt;
not disabled by a user option, otherwise make a file copy".&lt;/p&gt;
&lt;p&gt;The preferred format should be to store a file's names before its&lt;br /&gt;
contents.  Otherwise attempting to extract a single file can fail:&lt;br /&gt;
If B is archived after A as a hardlink to A, '7z x foo.7z B' has&lt;br /&gt;
bypassed A by the time sees B and realizes it needed A's contents.&lt;/p&gt;
&lt;p&gt;If each hardlink entry would contain the name of the file where&lt;br /&gt;
the actual contents is stored: I think p7zip should *not* blindly&lt;br /&gt;
link B to A when it sees an entry "B is a hardlink to A".  It&lt;br /&gt;
should report an error if it does not know A on the disk matches&lt;br /&gt;
the A in the archive or was just extracted from the archive.&lt;br /&gt;
Otherwise '7z x foo.7z B' could get an old copy of B (linked to&lt;br /&gt;
old A on the disk) instead of the one in the archive.&lt;/p&gt;&lt;/div&gt;</summary></entry></feed>
