Right-click the icon of 7-Zip File Manager, and then click <B>Run as administrator</B>.\r
Then you can change file associations and some other options.</P>\r
\r
-<H4>What version of 7-Zip is more stable?</H4>\r
-<P>Now there one main version of 7-Zip:</P>\r
+<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
+\r
+<P>You can increase compression ratio with the following methods:</P>\r
<UL>\r
-<LI>7-Zip 9.20 - it's revision 20 of 7-Zip 9 (started in 2009)\r
+ <LI>Increase dictionary size. It can help when 'qs' is not used.</LI>\r
+ <LI>Specify '<B>qs</B>' in <B>Parameters</B> field (or use <B>-mqs</B> switch for command line version).</LI>\r
</UL>\r
-<P>Latest beta versions can fix some bugs of previous versions.\r
-So they can be more stable in some cases. \r
-In general it's safe to use latest beta version.</P>\r
\r
-<H4>Why do the add, delete and update operations not work for some existing archives?</H4>\r
-<P>These operations didn't work only in old versions of 7-Zip. \r
-Latest 7-Zip supports any operations with "solid" archives.</P>\r
+<P>If you think that unusual file order is not problem for you, \r
+and if better compression ratio with small dictionary is more important for you,\r
+use '<B>qs</B>' mode.</P>\r
\r
<H4>Why can't 7-Zip open some ZIP archives?</H4>\r
<P>In 99% of these cases it means that the archive contains incorrect headers.\r
<P>There are also some ZIP archives that were encoded with methods unsupported by 7-Zip,\r
for example, WAVPack (WinZip).</P>\r
\r
+<H4>Why can't 7-Zip open some RAR archives?</H4>\r
+<P>7-Zip 9.20 supports RAR 2/3/4 formats only and doesn't support RAR5 archives.\r
+But latest versions of 7-Zip supports RAR5 archives.</P>\r
+\r
<H4>Why does drag-and-drop archive extraction from 7-Zip to Explorer use temp files?</H4>\r
<P>7-Zip doesn't know folder path of drop target.\r
Only Windows Explorer knows exact drop target.\r
<H4>How can I install 7-Zip in silent mode?</H4>\r
\r
<P>For exe installer: Use the "/S" parameter to do a silent installation and the "/D=dir" parameter \r
-to specify the "output directory". These options are case-sensitive. \r
-7-Zip uses the NSIS installer by Nullsoft.</P>\r
+to specify the "output directory". These options are case-sensitive.</P>\r
\r
<P>For msi installer: Use the /q INSTALLDIR="C:\Program Files\7-Zip" parameters.</P>\r
\r
+\r
+<H4>How can I recover corrupted 7z archive?</H4>\r
+\r
+<P>There are some possible cases when archive is corrupted:\r
+<UL>\r
+ <LI>You can open archive and you can see the list of files, but when you press \r
+ Extract or Test command, there are some errors: Data Error or CRC Error.\r
+ <LI>When you open archive, you get message "Can not open file 'a.7z' as archive"\r
+</UL>\r
+\r
+<P>It's possible to recover some data. Read about recovering procedure:\r
