+<H4>Why 7z archives created by new version of 7-Zip can be larger than archives created by old version of 7-Zip?</H4>\r
+\r
+<P>New versions of 7-Zip (starting from version 15.06) use another file sorting \r
+order by default for solid 7z archives.</P>\r
+\r
+<P>Old version of 7-Zip (before version 15.06) used file sorting "by type" ("by extension").</P>\r
+<P>New version of 7-Zip supports two sorting orders:</P>\r
+<UL>\r
+ <LI>sorting by name - default order.</LI>\r
+ <LI>sorting by type, if '<B>qs</B>' is specified in <B>Parameters</B> field in "Add to archive" window, \r
+ (or <B>-mqs</B> switch for command line version).</LI>\r
+</UL>\r
+\r
+<P>You can get big difference in compression ratio for different sorting methods,\r
+if dictionary size is smaller than total size of files.\r
+If there are similar files in different folders, the sorting "by type" can provide \r
+better compression ratio in some cases.</P>\r
+\r
+<P>Note that sorting "by type" has some drawbacks.\r
+For example, NTFS volumes use sorting order "by name", so if an archive uses \r
+another sorting, then the speed of some operations for files with unusual order \r
+can fall on HDD devices (HDDs have low speed for "seek" operations).</P>\r
