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>7-Zip 9.20 - it's revision 20 of 7-Zip 9 (started in 2009)\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
-<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>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>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
+\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
for example, WAVPack (WinZip).</P>\r
\r
<H4>Why can't 7-Zip open some RAR archives?</H4>\r
-<P>7-Zip still doesn't support new RAR 5 format. 7-Zip supports RAR 2/3/4 formats only.</P>\r
-\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
\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
+<P>For exe installer: Use the "/S" parameter to do a silent installation and the /D="C:\Program Files\7-Zip" parameter \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
<P>To compile sources you will need Visual C++ 6.0 or a later version. \r
Some files also require a new Platform SDK from microsoft.com:</P>\r
-<A href="http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdk-full.htm"><B>\r
-http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdk-full.htm</B></A>\r
-or\r
-<A href="http://www.microsoft.com/msdownload/platformsdk/sdkupdate/"><B>\r
-http://www.microsoft.com/msdownload/platformsdk/sdkupdate/</B></A>\r
\r
<P>If you are using MSVC, specify the SDK directories at the top of the "Include files" and \r
"Library files" directory lists. These can be found under "Tools / Options / Directories".</P>\r
Any other code in your application can be licensed as you wish.\r
This scheme allows users and developers to change LGPL'ed code and recompile\r
that DLL. That is the idea of free software. Read more here: \r
