Thank you for ikimi's delivery.

­popular and easy-to-use compression tools, support for mouse drag and drop and shell expansion, perfect support for ZIP files, built-in programs can unlock CAB, ARJ, LZH, TAR, GZ, UUE, BZ2, JAR, ISO and other types of compressed files.

­with an estimated compression function, you can get the approximate compression ratio of each of the three compression methods with ZIP and RAR before compressing the file; it has history and favorites functions; the compression ratio is quite high, while relatively low resource consumption, fixed compression, multimedia compression and multi-volume self-release compression are not available in most compression tools.

­important note: due to major vulnerabilities in the ACE module, WinRAR no longer supports ACE format compression files since 5.70 beta 1, and WinRAR rarely released the simplified Chinese version of beta version at the first time. WinRAR 5.70 beta2 is also the first simplified Chinese version of WinRAR after blocking this vulnerability.

­download from the official website (even if authorized, there will be advertising pop-up windows):

­WinRAR-updates to the latest version

­version 5.70 beta 2

­1. The find command and the disk and folder drop-down list have been renamed to search area.

­in addition to the existing options, it also includes a new "selected items" option, which is limited to the

­the selected files and folders are searched in the WinRAR file list.

­2. The find command displays the number of items found in the status bar.

­3. Switching-ta,-tb,-tn,-to now allows any number of modifier parameters in the same parameter

­set the same date for all specified times. For example,-tamc20190215 will handle the

­files modified and created after 2019-02-15.

­the new'o' modifier allows you to switch from AND to OR logic, so-tamco20190215

­contains files that were modified or created after 2019-02-15. It also allows you to use the same command line

­specify multiple time filter parameters with different dates, for example:

­- taco20190201-tbmo20190210

The ­- ta and-tn parameters also include files that exactly match the specified date. -tb and-to parameters

­these files are not included.

­4. The Diagnostic messages window displays the archive name in a separate column for a lengthy archive name

­provide better news visibility.

­5. The-isnd [-] parameter in WinRAR command line mode allows you to override the

­enable sound this option. Use-isnd to turn on sound notification, and use-isnd- to change it

­close.

­6. Problem fix:

­a) it has been fixed that disabling the compressed file list column also affects the Type column within the archive, and

­the problem of leaving it blank

­b) fixed that if the wrong global password is set, without name encryption, from the

­WinRAR will infinitely issue "the specified password is incorrect" when extracting encrypted files from the RAR archive

­the problem with this message

­c) fixed the "file list / file / specific size" option in the WinRAR settings in the archive

­problems that do not work.

­version 5.70 beta 1

­21. Nadav Grossman from Check Point Software Technologies

­introduced us to security vulnerabilities in the UNACEV2.DLL library. The above vulnerability can create files in any folder inside or outside the target folder when unzipping the ACE archive.

­WinRAR uses this third-party library to extract ACE files. UNACEV2.DLL has not been updated since 2005 and we have no access to its source code. So we decided to give up support for the ACE archive format to protect the security of WinRAR users.

­We thank Check Point Software Technologies for reporting the above issues.
