-<H4>Why do the add, delete and update operations not work for some existing archives?</H4>
-<P>These operations didn't work only in old versions of 7-Zip. 
-Latest 7-Zip supports any operations with "solid" archives.</P>
+<P>You can get big difference in compression ratio for different sorting methods,
+if dictionary size is smaller than total size of files.
+If there are similar files in different folders, the sorting "by type" can provide 
+better compression ratio in some cases.</P>
+
+<P>Note that sorting "by type" has some drawbacks.
+For example, NTFS volumes use sorting order "by name", so if an archive uses 
+another sorting, then the speed of some operations for files with unusual order 
+can fall on HDD devices (HDDs have low speed for "seek" operations).</P>
+
+<P>You can increase compression ratio with the following methods:</P>
