WinRAR 5.70 Beta 2 64-bit for PC Windows

Bugs fixed:
Fixed a crash and security vulnerability when unpacking corrupt RAR4 archives.
"Extract to a specified folder" command was missing in context menu in WinRAR file list when right clicking an archive.

Added support for Unix extended timestamp extra field (0x5455 extra field tag) in ZIP archives. Such timestamps are used by InfoZip to store UTC file time additionally to standard ZIP local time. Now WinRAR reads and sets such timestamps when extracting.
"Run", "Open in associated application", "Show archive contents" items are added to right click menu in WinRAR file list. So you can right click SFX archive or archive file with non-archive extension like .docx and choose if you wish to browse its contents, to run or open it. These items are present only in the file management mode and are not available inside of archives.
"File types to open as archives first" option is moved from "Settings/Archives" to "Settings/Compression". Now it works only outside of archives to avoid conflicts with "Settings/Viewer/ Unpack everything for" option.
Default folders for archives and extracted files are moved from "Settings/Compression" to "Settings/Paths" dialog page.
Bugs fixed:
Some files in TAR archives could be unpacked with full paths even if "Extract relative paths" option was enabled.

Previous versions ignored files with invalid UTF-8 names inside of ZIP archives. Now WinRAR extracts such files, even though their names may include arbitrary text after unpacking.
Bugs fixed:
5.50 beta 1 could crash when extracting some of broken RAR4 archives.
"Settings/Viewer/Unpack everything for" was ignored for files matching "Settings/Archives/File types to open as archives first" masks. Now it is changed, so "Unpack everything for" has a higher precedence for archived files. Files inside of archive matching "Unpack everything for" masks are processed according to that option even if they are also matched by "File types to open as archives first" masks.

WinRAR and command line RAR use RAR 5.0 archive format by default. You can change it to RAR 4.x compatible format with "RAR4" option in archiving dialog or -ma4 command line switch.
Use "Set master password" button in "Organize passwords" dialog to encrypt saved password records and protect them from unauthorized access.
Prompt proposing to set the master password is displayed when storing a password in compression profile. You can enter the master password to encrypt password data stored in Registry and protect it from unauthorized access. You will need to enter the master password in password prompt dialog to access such compression profile after that.
By default, WinRAR uses AES-256 in CTR mode to encrypt ZIP archives. While AES-256 is significantly more secure than ZIP 2.0 legacy encryption algorithm, it can be incompatible with some older unzip software. If compatibility with such tools is required, you can enable "ZIP legacy encryption" option in the password dialog or use -mezl switch in the command line mode.
Added extraction support for .LZ archives created by Lzip compressor.
Modern TAR tools can store high precision file times, lengthy file names and large file sizes in special PAX extended headers inside of TAR archive. Now WinRAR supports such PAX headers and uses them when extracting TAR archives.
New "Store modification time" option on "Time" page of archiving dialog can be used to prohibit storing the file modification time in RAR 5.x archives. Former "High precision modification time" option is replaced by "High precision time format".
New "Full paths in title bar" option in "Settings/General" dialog. If enabled, the full path of currently opened folder or archive is displayed in WinRAR title bar.
New "Settings/Archives" page provides "File types to open as archives first" group of options. Here you can define how Enter or double click on a file with non-archive extension and archive contents should be processed in WinRAR file list. Examples of such files are .docx or self-extracting .exe archives. You can instruct WinRAR to open such files as archives, to run them, to handle them similarly or differently inside and outside of archives, to never run specified file types even if they do not include any archived contents.
New "Copy full names to clipboard" command in "File" menu places full names of selected files to clipboard.
LZ and ZIPX are added to list of associations in Settings/Integration dialog.
LZ and ZIPX extensions are added to default list of formats for -ms switch ("Specify file types to store") invoked without parameters.
You can specify 'f' charset value in -sc switch to use UTF-8 encoding.
RAR "lt" and "vt" commands display file times with nanosecond precision. Such precision is used in RAR5 archives created by RAR/Unix 5.50 and newer. Archives created by WinRAR have 100ns file time precision.
Only '+', '-' and '1' precision modifiers are supported in -ts switch now. Use '+' to store the file time with maximum precision, '-' to omit the file time and '1' to store it with 1 second precision. Intermediate precision modes previously defined with '2' and '3' modifiers are not available in RAR 5.0 archive format and ignored by -ts switch.
If a wrong password is entered when unpacking an encrypted file in RAR5 archive, WinRAR proposes to enter a valid password for same file again instead of aborting extraction.
File path information is displayed if mouse pointer is placed over a name of archiving file in the operation progress window.
Name of currently active compression profile is displayed in the archiving dialog above "Profiles..." button.
If "Find" command is invoked from inside of archive subfolder, "File names to find" will include the path to this subfolder. So "Find" will search only starting from this subfolder.
Bugs fixed:
WinRAR failed to unpack files in ZIP archives compressed with XZ algorithm and encrypted with AES.
If "Windows progress bars" option in WinRAR settings was turned off and "Put each file to separate archive" archiving mode was used, "gold" part of total progress bar did not display the compressed data ratio correctly.
SFX archive extraction progress was incorrect in case of multivolume SFX archive with total volume size exceeding 4 GB.
If archived folder name included trailing spaces, if user selected and extracted some folders in non-root archive folder and if "Allow potentially incompatible names" extraction option was turned off, WinRAR could lose one or more leading characters in extracted folder name.
If only creation or only last access file time was stored in RAR5 archive with 1 second precision, such as with -ma5 -tsm- -tsa1 switches, this stored time was ignored when extracting.

- "Name encoding" submenu in "Options" menu allows to select encoding for archived file names. This selection affects archive browsing and extraction commands. You can use Ctrl+E keyboard shortcut to access this menu quickly. It can be useful when unpacking an archive without Unicode file names.
- If RAR recovery volumes (.rev files) are present in the same folder as usual RAR volumes, archive test command verifies .rev contents after completing testing .rar files. If you wish to test only .rev files without checking .rar volumes, you can select .rev files in WinRAR file list and apply "Test" only to them or run: rar t arcname.part1.rev in the command line.
- While NTFS file system permits file names with trailing spaces and dots, a lot of Windows programs fail to process such names correctly. If "Allow potentially incompatible names" option in "Advanced" page of extraction dialog is turned off, WinRAR removes trailing spaces and dots, if any, from file names when extracting. This option is turned off by default. Command line RAR also removes trailing spaces and dots when extracting unless -oni switch is specified.
- Previously "Synchronize archive contents" update mode(-as command line switch) aborted if some of archiving folders could not be read. Now WinRAR continues performing the operation and preserves archived files matching unreadable folders.
- WinRAR Shift+Del delete command can be used to delete folders containing non-standard file names with trailing spaces and dots. Usual delete to Recycle Bin also as Shift+Del in previous WinRAR versions cannot delete such folders.
- You can drag folders from folder tree panel and drop them to other programs or Desktop to copy or unpack them. Drag the archive icon in tree panel root to unpack the entire archive.
- "New folder" button in extraction dialog proposes a new folder name based on archive name instead of generic "New Folder".
- Command line RAR version information:
* if -iver switch is specified, RAR displays the version number and quits. You can run just "RAR -iver";
* "x86" or "x64" is displayed in Windows RAR version information both for -iver and in the copyright title for other commands.
- If -p switch is used without optional <pwd> parameter, a password can be also set with file redirection or pipe. For example: rar -p myarc.rar myfiles < psw.txt
- Command line RAR treats 'arcname.partN' as 'arcname.partN.rar' if 'arcname.partN' does not exist and 'arcname.part#.rar' exists.
- Improvements in 7z archives support:
* "Solid" status is correctly detected and reported for 7z archives in WinRAR "Info" command;
* dictionary size is displayed for LZMA and LZMA2 7z archives in WinRAR "Info" command;
* unknown packed size for files inside of 7z solid block is denoted as '?' instead of '0' when browsing the archive contents in WinRAR.
- Maximum comment length for RAR archives is increased from 64 to 256 KB. Since SFX script commands are stored in archive comment, it allows a longer main and license text in SFX archives.
- Size of default WinRAR viewer font is scaled up properly in Windows high DPI mode.
- Switch -scul can be used to process big endian UTF-16 list files as well, provided that they have a correct byte order mark. Previously it allowed only little endian file lists.
- Minimum supported Windows version is Windows XP SP3 now. WinRAR will not run in Windows XP without service packs.
- "Settings/File list/Allow all uppercase names" option is removed. This option was intended to simplify transition from MS DOS to Windows and is not needed anymore.
# Bugs fixed:
- WinRAR 5.31 x64 "Compress and email" command did not work with Microsoft Outlook x64;
- if WinRAR 5.31 version for one of right to left languages was installed in Windows with English or other not right to left system language, WinRAR could change Windows Explorer layout to right to left;
- if archive was stored in a folder without "Write" permission and if archive contents was extracted with drag and drop to a writable folder, WinRAR issued an unnecessary privileges elevation prompt.

# Bugs fixed:
- if ZIP archive contained an archive comment shorter than 24 characters, the comment page was not displayed in archive properties in Windows Explorer;
- 'WinRAR x *.rar' command crashed if complete .part1.rar, .part2.rar, ..., .partN.rar volume set was found when expanding *.rar mask.

# Bugs fixed:
- RAR exited with code 6 (file open error) instead of expected code 10 (no files found) if file name specified for archiving did not exist;
- WinRAR could issue an excessive sound notification in the middle of archiving if sound was enabled in WinRAR settings and "Put each file to separate archive" option turned on;
- WinRAR did not delete a temporary file if ZIP archive modification was aborted, because ZIP archive had the read-only attribute;
- WinRAR crashed if "Print file" command was applied to a file or folder without extension.

- Switch -scul can be used to process big endian UTF-16 list files, provided that they have the correct byte order mark. Previously it supported only little endian file lists.
- 5.40 beta 1 did not work on CPU without SSE2 instruction set.
- It could take excessively long time to cancel WinRAR "Repair" command on some corrupt archives.
- If "Generate archive name by mask" option was used and archive was created in a system protected folder requiring privileges elevation, mask was added to archive name twice.

No change log.

- "Name encoding" submenu in "Options" menu allows to select encoding for archived file names. This selection affects archive browsing and extraction commands. You can use Ctrl+E keyboard shortcut to access this menu quickly. It can be useful when unpacking an archive without Unicode file names.

- WinRAR Shift+Del delete command can be used to delete folders containing non-standard file names with trailing spaces and dots. Usual delete to Recycle Bin also as Shift+Del in previous WinRAR versions cannot delete such folders. Unlike Del command, Shift+Del removes files permanently, they are not moved to Recycle Bin. No additional prompts are issued for files with read-only and system attributes.
- You can drag folders from folder tree panel and drop them to other programs or Desktop to copy or unpack them. Drag the archive icon in tree panel root to unpack the entire archive.
- "New folder" button in extraction dialog proposes a new folder name based on archive name instead of generic "New Folder".
- Command line RAR version information:

- Command line RAR treats 'arcname.partN' as 'arcname.partN.rar' if 'arcname.partN' does not exist and 'arcname.part#.rar' exists. For example, it is allowed to run: RAR x arcname.part01 to start extraction from arcname.part01.rar
- Improvements in 7z archives support:
* "Solid" status is correctly detected and reported for 7z archives in WinRAR "Info" command;
* dictionary size is displayed for LZMA and LZMA2 7z archives in WinRAR "Info" command;
* unknown packed size for files inside of 7z solid block is denoted as '?' instead of '0' when browsing the archive contents in WinRAR.

- Information about the critical vulnerability in WinRAR self-extracting archives published in news in September and October 2015 is incorrect. Unfortunately mass media failed to recognize that what was described as WinRAR vulnerability is Windows OLE vulnerability patched in November 2014: Even if unpatched, this Windows OLE vulnerability does not introduce new risk factors for WinRAR SFX archives. No patches for WinRAR are needed.
- 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 will combine all parts and save them to extracted file. All parts must be stored in the same folder before starting extraction. "001" item is included to "Associate WinRAR with" list in "Settings/Integration" dialog.
- 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. For example: rar a backup c:ackup2015** will archive all '2015*' folders in c:ackup. Use -r switch to search for '2015*' also in c:ackup subfolders.
- "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. For example: rar lb -scur data > list.txt will produce Unicode list.txt with archived file names.
- 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. Such conversion is required for some Unix and OS X archives to correctly unpack non-English archived names in Windows. It works for Windows versions starting from Windows Vista.
- 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;
- WinRAR could not restore contents of NTFS alternate data stream saved with -os switch if it was split between different volumes.

# Bugs fixed:
- "Print file" command did not work with HTML files in Windows 10;
- if relative path to report file was specified, "Generate report" command created a report file in WinRAR start folder instead of current WinRAR folder;
- in some cases text scaling in SFX archive main and license dialogs in high DPI mode did not work, so text size was smaller than expected;
- changes in broken archive processing to handle invalid ZIP, ARJ and ISO archives more reliably;
- RAR "l" and "v" list commands added unneeded spaces after file names shorter than 12 characters.

# Information about the critical vulnerability in WinRAR self-extracting archives recently published in news is incorrect. Unfortunately mass media failed to recognize that what was described as WinRAR vulnerability is Windows OLE vulnerability patched in November 2014: Even if unpatched, this Windows OLE vulnerability does not introduce new risk factors for WinRAR SFX archives.
# "Import/Export" commands:
- WinRAR performs the additional validation of Settings.reg contents for "Import settings from file" command to prevent importing Registry keys unrelated to WinRAR settings;
- WinRAR specifies the full path to regedit.exe tool to prevent running copies of "regedit" from other folders.
# Bugs fixed:
- If 'file' and 'file.exe' were present in the same folder and user double clicked on 'file', WinRAR could start 'file.exe' instead;
- "Generate report" command could create a report in wrong folder, not that with selected files;
- RAR could crash when unpacking .rar archives with corrupt file headers. Fixed now.

- It is allowed to specify environment variables in path to external viewer in WinRAR "Settings/Viewer" dialog.
- Folder wildcards behavior is changed, so command like: rar a backup c:ackup2015** will search for '2015*' folders only in c:ackup. Add -r switch if you wish to search also in all c:ackup subfolders.
- If wrong password is specified when extracting an encrypted file in RAR5 archive, WinRAR will not create folders contained in file path. Previous versions created file path folders even if file extraction failed because of wrong password.
# Bugs fixed:
- "Delete files after archiving" option of default compression profile was ignored in drag&drop operations in previous beta.

- WinRAR treats .txz archive extension as .tar.xz and opens .txz contents in a single step.
- If you drag a file from another application to WinRAR holding Shift button, a file will be deleted after archiving. Previous versions ignored Shift state here.
- WinRAR ignores "Turn PC off when done" option in case of read and write errors if user pressed Cancel in repeat read or repeat write dialogs.
# Bugs fixed:
- archive comment is displayed also in empty ZIP archives. Previous versions did not display it if ZIP archive did not contain any files;
- Explorer window containing a temporary folder with unpacked file could be opened when attempting to view an archived file in a corrupt ZIP archive. File entry in a corrupt ZIP could have a wrong "hard drive" icon.
