If Windows User Account Control prevents extracting or archivingcommands to create files in system protected folders, WinRAR attemptsto start its another copy with administrator privileges to completethe operation. It is necessary to confirm privileges elevationin response to User Account Control prompt to allow such secondWinRAR copy to run.2. You can drag files in Explorer with right mouse button, drop themto some folder and select WinRAR archiving commands in context menuto create an archive with these files in the destination folder.3. It is possible to use WinRAR.ini file instead of Registry to storeWinRAR settings. You may prefer such approach if you plan to installWinRAR to removable media, such as USB flash drive, and then run iton different computers.See "WinRAR.ini file" topic in "Configuration settings" chapterof WinRAR help for details.4. Added extraction support for ZIP and ZIPX archives usingXZ compression algorithm.5. If ZIP or ZIPX archive contains any compression algorithms exceptusual "Store" or "Deflate", algorithm names are displayedin "Version to extract" field of archive information dialog.Algorithms with names unknown to WinRAR will be assigned "m"name, where "num" is a compression algorithm numeric identifier.6. "Open with WinRAR" command is available in Windows context menusfor archive formats supported by WinRAR. It can be turned offwith "Open with WinRAR (for usual archives)" option in WinRAR"Settings/Integration/Context menu items..." dialog.7. Command line RAR can read the default set of switches from rar.inifile stored in RAR program folder. Previously it was possible todefine only the same set of switches for all RAR command with"switches=" string. Now rar.ini also allows to specifyseparate switch sets for individual RAR commands usingthe following syntax:switches_=For example:switches_a=-m5 -sswitches_x=-o+8. Command "ch" supports switches -tl, -cu, -cl also for ZIP archives.Previously "ch" allowed these switches only for RAR archive format.9. For archive formats lacking file time information, such as .bz2,.xz and .Z, WinRAR sets container archive modification timeto extracted files. It does not apply to tar.bz2, tar.xz and tar.Z,which use file time stored in tar headers.10. "Keep broken files" extraction option is supported for bzip2 archives.11. WinRAR icon in Windows context menus is scaled up correctlyin high DPI screen modes such as 150% or 200% of normal text size.12. It is possible to disable WinRAR "Benchmark" command with"Benchmark" variable of HKEY_CURRENT_USER\Software\WinRAR\PolicyRegistry key. In multi-user environment "Benchmark" command mightabuse shared computational resources. See "Registry variables" topicin "Configuration settings" chapter of WinRAR help for more details.13. Additionally to "sfxcmd" variable containing the entire command line,SFX module sets "sfxpar" variable containing command line parametersonly, without leading SFX module name. These variables are set beforestarting a program specified in "Setup" command.14. File overwrite prompt in console RAR displays the size and modificationtime for existing and new files.15. When archiving from stdin with -si switch, RAR sets the current systemtime to modification time of archived file. Previous version did notset this time at all.16. It is possible to use -si and -v switches together. Previousversions did not allow to create volumes when archiving from stdin.17. Warning is issued when starting unpacking 4 GB or larger filefrom RAR or ZIP archive to FAT32 patition, so user may cancelthe operation. FAT32 does not support files of such size.Also this warning is issued when starting to create RAR archivewith "Store" (-m0) method if estimated archive size is 4 GB or more.18. "Select all" button in "Settings/Integration" dialog is renamed to"Toggle all". Now it deselects archive formats if all they arealready selected.19. "Delete archive" extraction option correctly removes all .zip and .7zvolumes. Previously it removed only the first volume in the setfor these archive formats.Version 4.20 beta 31. "Estimate" function in WinRAR "Info" command is adjusted tofaster WinRAR 4.20 compression when calculating the expectedcompression time.2. GUI SFX module -sp switch passes parameters to setup applicationonly if no other parameters were specified in "Setup" commandin SFX script. So "Setup" command has a higher priority than -sp.Regardless of -sp presence, setup application can readthe full SFX command line from sfxcmd environment variable.3. "Save current settings" button in "Advanced SFX options" dialogis now available only when converting an existing archive to SFX.Options saved with this button are applied only to convert to SFXoperation.If you create or update SFX archive, only SFX options storedin default compression profile are used. Options savedin "Advanced SFX options" dialog are ignored for these operations.Version 4.011. Added support for file sizes stored in binary format in TAR archives.Some TAR archives use the binary size format instead of octalfor files larger than 8 GB.2. Bugs fixed:a) "Repair" command failed to properly reconstruct structureof RAR archives, which contained at least one file with packedsize exceeding 4 GB.This bug did not affect the recovery record based repair.It happened only if recovery record was not found and WinRARperformed reconstruction of archive structure;b) even if "Do not extract paths" option in "Advanced" part ofextraction dialog was set as the default, WinRAR still unpackedfile paths if called from Explorer context menu;c) after entering a wrong password for encrypted ZIP archive,sometimes WinRAR ignored subsequent attempts to enter a validpassword;d) "Wizard" command did not allow to create self-extracting and multivolume archives, when compressing a single folderor a file without extension;e) "Import settings from file" command did not restore multilinecomments in WinRAR compression profiles;f) when converting RAR volumes having name1.name2.part.rar name format,"Convert archives" command erroneously removed ".name2" name part.So resulting archive had name1.rar file name instead of expectedname1.name2.rar;g) RAR could crash when creating a new archive with -agNNN switchif archive number in generated name was 110 or larger;h) WinRAR failed to display non-English file names in 7-Zip archivesproperly if they used a non-default code page. It was the displayonly problem, such names were unpacked correctly.WinRAR 3.93 Final:1. Bugs fixed:a) in WinRAR 3.92 -xd:pathfolder switch could also exclude folders,which path does not match the path specified in the switchand only the folder name is the same as specified;b) switches -y -or did not work correctly together. Switch -or wasignored in presence of -y.WinRAR 3.92 Final:1. If you start WinRAR command from Explorer context menu in multiple monitor configuration, the command dialog will be displayed on the same monitor as context menu. In previous versions it was always displayed on primary monitor.2. WinRAR "Compress and email..." context menu command adds the archive name to email subject. Previous versions left the subject blank.3. In RAR 3.91 -x switch could also exclude folders from archiving even if mask contained wilcard characters and did not contain a path. For example, -x*. excluded all those folders, which do not have the extension in the name. Now -x switch uses RAR 3.80 approach for masks without path, excluding folders only if mask does not contain wildcards and matches the folder name exactly.4. Bugs fixed:a) WinRAR 3.91 reported the incorrect "Unexpected end of archive" error, when opening an empty ZIP archive created with "New WinRAR ZIP archive" context menu command;b) if "Delete archive" option was enabled when unpacking several ZIP archives and if one of archives was damaged, WinRAR did not delete archives after the damaged one, even if they were unpacked successfully;c) if file matched two different masks in RarFiles.lst, WinRAR could select the last match. Normally, if neither of masks is a subset of another, the first match must be chosen.WinRAR 3.91 Final:1. This version can decompress 7-Zip archives created with LZMA2 algorithm.2. Now a password is requested only once when unpacking 7z archives with encrypted file names from context menu. WinRAR 3.90 asked it twice.3. This version can unpack tar.bz2 archives consisting of several smaller bz2 streams merged together. Previous versions unpacked only the first nested bz2 stream in such composite archive.4. WinRAR displays CRC32 of files inside of usual .gz (not .tar.gz) archives. Previous versions left this field blank for GZIP files.5. Bugs fixed:a) WinRAR 3.90 displayed "Save" button instead of "Open" or "OK" in "Find archive" dialog ("Open archive" command in "File" menu and "Browse..." command in archiving dialog);b) WinRAR could display incorrect file names when browsing malformed ZIP archives;c) WinRAR 3.90 failed to decompress LZH archives created with "-lh7-" algorithm;d) WinRAR 3.90 could fail to delete a part of files after archiving if delete to Recycle Bin was enabled. This bug was present when working in Windows XP, but not in Windows Vista and Windows 7;e) when unpacking ISO file using WinRAR "Extract files..." command in Explorer context menu, WinRAR could unpack same archived files twice during the same operation. It displayed the overwrite prompt when unpacking files for the second time;f) hexadecimal search in WinRAR 3.90 "Find" command and console RAR "ih" command failed to find matches if first byte in search string was greater than 127.&160;&160;&160;&160;
