WinRAR 5.70 Beta 2 64-bit for PC Windows

# SFX module sets sfxstime environment variable, which contains the module start time in "YYYY-MM-DD-HH-MM-SS-ms" format. You can specify it in Path command if you need to generate a time based unique installation path, such as "Path=myapp-%sfxstime%".
# Fewer password requests in following cases in "Convert archives" command:
- if "Convert archives" is applied to archive with encrypted file names, which contents is currently displayed in WinRAR;
- if archive produced by "Convert archives" includes encrypted file names.
# Bugs fixed:
- RAR volumes renamed from standard .part1.rar, .part2.rar to .001, .002 are recognized and processed correctly now. Previous beta opened them as set of usual split files, not as RAR volumes;
- reports produced with "Generate report" command contained invalid CRC32 checksums for non-archived files;
- "rar x arcname.rar d:" command unpacks files to d: current folder. Previous version unpacked them to d: root folder;
- archive comment was not encrypted if added to archive with encrypted headers using "c" command without -hp switch. This beta encrypts an archive comment in such case.

- Added extraction of multipart ZIP archives created by 7-Zip.
- Added extraction of files split to multiple parts with .001,.002, ..., extensions. You can open .001 file as a usual archive and then unpack its contents.
- WinRAR file list allows to use mouse Back and Forward buttons or Alt+Left and Alt+Right keyboard shortcuts to navigate in recently visited folders.
- Folder wildcards are allowed in RAR command line in file names to archive.
- "Extract" button in SFX archive is changed to "Pause" when extraction is started, so it is possible to pause SFX extraction and resume it later.
- "Skip encrypted" option in "Find files" dialog to silently skip encrypted archives while performing search command.
- Archive test command works for tar.gz, tar.bz2 and tar.xz archives. Since TAR format does not provide file data checksums, WinRAR checks only validity of GZIP, BZIP2 or XZ container.
- Adding a new string to WinRAR diagnostic messages window could be slow and affect the operation performance in case of thousands of errors. Now it works fast regardless of errors number.
- New 'R' object for -sc switch defines encoding of console RAR messages sent to redirected files and pipes.
- Sleep time parameter in -ri<priority>[:<sleep_time>] switch is adjusted to lower its impact to RAR performance and especially to recovery record related operations. Higher sleep time values are needed to reduce the system load to same level as in previous versions.
- Console RAR "l" and "v" commands display file time in YYYY-MM-DD format.
- When extracting RAR and ZIP archives created in Unix, WinRAR maps decomposed Unicode characters to precomposed.
- Modification time is set for all folders created when unpacking .7z archives. Previous versions set it only for non-empty folders.
- WinRAR prevents a computer to go to sleep by inactivity timeout until current operation, such as archiving, extraction or another archive processing, is done.
- Total progress bar is displayed when extracting .arj, .lzh and .cab archives (except multivolume archives).
- Progress bar is displayed when deleting files after archiving and when clearing "Archive" attribute of archived files.
- "Test" command also verifies contents of NTFS alternate data streams in RAR 3.x - 5.x archives. Previously their contents was checked only during extraction command.
# Bugs fixed:
- console RAR crashed instead of displaying an overwrite prompt when attempting to add files to already existing volumes;
- console RAR "lt" command did not display seconds in file timestamp;
- WinRAR failed to decompress .xxe files if they did not include "section N of xxencode" string in the body;
- RAR could not restore contents of NTFS alternate data stream saved with -os switch if it was split between different volumes.

# New
* "Drag and drop context menu" options in "Settings/Integration/Context menu items" dialog allow to disable WinRAR archiving and extraction commands in context menu displayed after dragging and dropping files with right mouse button.
* If winrar.ini file is present in the same folder as WinRAR installer, winrar.ini will be copied to WinRAR program folder after completing installation.
* While previous versions could produce RAR5 volumes of slightly smaller than requested size sometimes, such situation is less likely now. In most cases volume size equals to specified by user.
* Now by default WinRAR skips symbolic links with absolute paths in link target when extracting. You can enable creating such links with "Allow absolute paths in symbolic links" option on "Advanced" page of extraction dialog or with -ola command line switch.
# Bugs fixed:
* WinRAR 5.20 issued unnecessary user account control (UAC) prompt, when running an executable from archive stored in UAC protected folder. Since nothing is extracted to folder containing an archive in such case, UAC prompt is not needed;
* WinRAR could overwrite files with read-only attribute only when unpacking RAR and ZIP archive formats. Now it is also implemented for other archive formats supported by WinRAR;
* "Elapsed time" and "Time left" were displayed incorrectly when applying "Convert" command to multiple archives and enabling "Add recovery record" option.

# Bugs fixed: if several files from different folders were selected and extracted using "Flat folders view" file list mode and "Extract relative paths" extraction option, WinRAR could truncate paths of some of these files. It did not happen if entire file list contents or a single file was selected.

* "Drag and drop context menu" options in "Settings/Integration/Context menu items" dialog allow to disable WinRAR archiving and extraction commands in context menu displayed after dragging and dropping files with right mouse button.
* If winrar.ini file is present in the same folder as WinRAR installer, winrar.ini will be copied to WinRAR program folder after completing installation.
* While previous versions could produce RAR5 volumes of slightly smaller than requested size sometimes, such situation is less likely now. In most cases volume size equals to specified by user.

* If Windows User Account Control prevents extracting or archiving commands to create files in system protected folders, WinRAR attempts to start its another copy with administrator privileges to complete the operation. It is necessary to confirm privileges elevation in response to User Account Control prompt to allow such second WinRAR copy to run.
* You can drag files in Explorer with right mouse button, drop them to some folder and select WinRAR archiving commands in context menu to create an archive with these files in the destination folder.
* It is possible to use WinRAR.ini file instead of Registry to store WinRAR settings. You may prefer such approach if you plan to install WinRAR to removable media, such as USB flash drive, and then run it on different computers.
* Added extraction support for ZIP and ZIPX archives using XZ compression algorithm.
* If ZIP or ZIPX archive contains any compression algorithms except usual "Store" or "Deflate", algorithm names are displayed in "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.
* "Open with WinRAR" command is available in Windows context menus for archive formats supported by WinRAR. It can be turned off with "Open with WinRAR (for usual archives)" option in WinRAR "Settings/Integration/Context menu items..." dialog.
* Command line RAR can read the default set of switches from rar.ini file stored in RAR program folder. Previously it was possible to define only the same set of switches for all RAR command with "switches=" string. Now rar.ini also allows to specify separate switch sets for individual RAR commands using the following syntax:
- switches_=
- For example:
- switches_a=-m5 -s
- switches_x=-o+
* Command "ch" supports switches -tl, -cu, -cl also for ZIP archives. Previously "ch" allowed these switches only for RAR archive format.
* For archive formats lacking file time information, such as .bz2,.xz and .Z, WinRAR sets container archive modification time to extracted files. It does not apply to tar.bz2, tar.xz and tar.Z, which use file time stored in tar headers.
* "Keep broken files" extraction option is supported for bzip2 archives.
* WinRAR icon in Windows context menus is scaled up correctly in high DPI screen modes such as 150% or 200% of normal text size.
* It is possible to disable WinRAR "Benchmark" command with "Benchmark" variable of HKEY_CURRENT_USERSoftwareWinRARPolicy Registry key. In multi-user environment "Benchmark" command might abuse shared computational resources. See "Registry variables" topic in "Configuration settings" chapter of WinRAR help for more details.
* Additionally to "sfxcmd" variable containing the entire command line, SFX module sets "sfxpar" variable containing command line parameters only, without leading SFX module name. These variables are set before starting a program specified in "Setup" command.
* File overwrite prompt in console RAR displays the size and modification time for existing and new files.
* When archiving from stdin with -si switch, RAR sets the current system time to modification time of archived file. Previous version did not set this time at all.
* It is possible to use -si and -v switches together. Previous versions did not allow to create volumes when archiving from stdin.
* Warning is issued when starting unpacking 4 GB or larger file from RAR or ZIP archive to FAT32 patition, so user may cancel the operation. FAT32 does not support files of such size. Also this warning is issued when starting to create RAR archive with "Store" (-m0) method if estimated archive size is 4 GB or more.
* "Select all" button in "Settings/Integration" dialog is renamed to "Toggle all". Now it deselects archive formats if all they are already selected.
* "Delete archive" extraction option correctly removes all .zip and .7z volumes. Previously it removed only the first volume in the set for these archive formats.

# Bugs fixed:
* "Extract each archive to separate folder" context menu command did not work properly and extracted all files to same folder if destination folder was protected with user account control (UAC).

# Bugs fixed:
* "Extract relative paths" option was ignored and full pathname was created when extracting a file from ZIP archive to a folder protected with user account control (UAC)
* if encrypted archived file was opened in external editor, modified and saved, previous beta stored this file back to archive without encryption.

- "Create WinRAR.ini file" command in "Export/Import" submenu of "Options" menu creates a new WinRAR.ini file and copies WinRAR settings from Registry to this file.
- Beta 1 documentation described "Global" keys in WinRAR.ini as Global/AppData, Global/Integration, Global/SaveSettings, when actually they are GlobalAppData, GlobalIntegration, GlobalSaveSettings (backslash instead of forward slash).
- Now WinRAR creates these keys in WinRAR.ini automatically if they do not already exist.
- Compression settings in "Convert archives" dialog were not saved after pressing "Save" button.
- First beta proposed "name.ext.ext.rar" instead of expected "name.ext.rar" archive name, when archiving "name.ext" folder.

* WinRAR can unpack TAR archives containing folders with pax extended headers. Previous versions failed to unpack them.
* "Keep broken files" extraction option is supported for 7-Zip archives.
* Bugs fixed:
- WinRAR 5.10 did not set "hidden", "read-only" and "system" file attributes when unpacking ZIP archives;
- WinRAR 5.10 failed to update self-extracting RAR archives containing nested ZIP archives stored without compression;
- ZIP archive created with "Do not store paths" option included unnecessary empty name records for folders;
- archived files could have 1 hour modification time error in Windows XP;
- deleting a file in RAR5 solid archive containing files stored with -ver switch caused such files to lose version information;
- black rectangles were displayed instead of toolbar buttons in 16- and 24- bit screen color modes and Windows custom text size larger than 100%.

- Added extraction support for ZIP and ZIPX archives using BZIP2, LZMA and PPMd compression.
- Added extraction support for 7z split archives (.7z.001, .7z.002, ...).
- Added support for AES-NI CPU instructions allowing to improve RAR encryption and decryption performance.
- Default theme images are scaled up with better quality in high DPI display mode.
- Environment variables, such as %temp%, can be used in "Files to add" field of archiving dialog.
- Switch -ai can be used when creating RAR archive, so predefined values, typical for file and folder, are stored instead of actual attributes. Previously this switch could be used only when extracting.

# Bugs fixed:
* failed to decompress multivolume encrypted RAR archives;
* "Update" command ("u" in command line mode) could update even files with same modification time;
* under rare conditions x86 version working in multithreaded mode on SSE2 enabled CPU could erroneously issue checksum error message for first file in valid RAR5 archive with BLAKE2sp checksums.

# More efficient implementation of "Keep broken files" extraction option (-kb switch in command line mode). Now it allows to recover more data from file split between RAR volumes if next volume is missing.
# Bugs fixed:
* "Create recovery volumes" command on "Options" page of archive information dialog was inaccessible if "Merge volume contents" option was enabled in WinRAR settings;
* if wrong password was entered for RAR archive with encrypted file names, previous beta applied such wrong password automatically, when opening the same archive again.
