-<H4>Why do the add, delete and update operations not work for some existing archives?</H4>\r
-<P>The current version of 7-Zip can't execute some operations with .7z archives that have been \r
-created with the "solid" option switched on. You can disable solid mode with -ms=off switch \r
-in command line</P>\r
-\r
-<H4>What about ACE archive support?</H4>\r
-<P>Support for ACE archives could be implemented in 7-Zip, if the source code \r
-of that format was available, and the license allowed it. The Unace.dll \r
-library from the authors of the ACE program is not \r
-compatible with the plugin interface of 7-Zip (Unace.dll works with files, but \r
-7-Zip only allows plugins to work with abstract streams). For this reason 7-Zip can't use \r
-Unace.dll without a complex wrapper.</P>\r
+<H4>How can I set file associations to 7-Zip in Windows 7 and Windows Vista?</H4>\r
+<P>You must run 7-Zip File Manager in administrator mode. \r
+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
 \r

-<H4>Why doesn't the command line version add files without extensions to an archive?</H4>\r
-<P>You're probably using a *.* wildcard. 7-Zip doesn't use the operating system's wildcard mask parser, \r
-and consequently treats *.* as any file that has an extension. \r
-To process all files you must use the * wildcard instead or omit the wildcard altogether.</P>\r
+<H4>What version of 7-Zip is more stable?</H4>\r
+<P>Now there one main version of 7-Zip:</P>\r
+<UL>\r
+<LI>7-Zip 9.20 - it's revision 20 of 7-Zip 9 (started in 2009)\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

 \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

+\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
+And Windows Explorer needs files (drag source) as decompressed files on disk.\r
+So 7-Zip extracts files from archive to temp folder and then \r
+7-Zip notifies Windows Explorer about paths of these temp files.\r
+Then Windows  Explorer copies these files to drop target folder.</P>\r
+\r
+<P>To avoid temp file usage, you can use Extract command of 7-Zip or \r

+\r
+<H4>Why doesn't -r switch work as expected?</H4>\r
+<P>In most cases you don't need -r switch.\r
+7-Zip can compress subfolders even without -r switch.</P>\r
+<P>Example 1:</P>\r
+<PRE>  7z.exe a c:\a.7z "C:\Program Files"</PRE>\r
+<P>compresses "C:\Program Files" completely, including all subfolders.</P>\r
+<P>Example 2:</P>\r
+<PRE>  7z.exe a -r c:\a.7z "C:\Program Files"</PRE>\r
+<P>searches and compresses "Program Files" in all subfolders of C:\ (for example, in "C:\WINDOWS").</P>\r
+If you need to compress only files with some extension, you can use -r switch:\r
+<PRE>  7z a -r c:\a.zip c:\dir\*.txt </PRE>\r
+<P>compresses all *.txt files from folder c:\dir\ and all it's subfolders.</P>\r
+\r
+<H4>How can I store full path of file in archive?</H4>\r
+<P>7-Zip stores only relative paths of files (without drive letter prefix).\r
+You can change current folder to folder that is common for \r
+all files that you want to compress and then you can use relative paths:</P>\r
+<PRE>\r
+  cd /D C:\dir1\\r
