流行好用的压缩工具，支持鼠标拖放及外壳扩展，完美支持 ZIP 档案，内置程序可以解开 CAB、ARJ、LZH、TAR、GZ、UUE、BZ2、JAR、ISO 等多种类型的压缩文件。重要提示：因ACE模块重大漏洞，WinRAR从5.70 beta 1始不再支持ACE格式压缩档。

Version 5.70

1. “Files to process” option on “Time” page of archiving dialog

allows to choose files based on modification, creation or last access

file time. Previously it was possible for modification time only.

2. Command line -ta, -tb, -tn, -to switches accept ‘m’, ‘c’ and ‘a’

modifiers after the switch name. So file time conditions can include

not only the file modification time as in previous versions,

but also creation and last access time.

Such switch can include multiple modifiers to set the same date

for all specified times. For example, -tamc20190215 will process files

modified and created after 2019-02-15.

New ‘o’ modifier permits to switch from AND to OR logic,

so -tamco20190215 includes files modified or created after 2019-02-15.

It is also allowed to specify several time filtering switches

with different dates in the same command line, like:

-taco20190201 -tbmo20190210

Switches -ta and -tn also include files matching the specified date

exactly. Switches -tb and -to exclude such files.

3. WinRAR file list can display creation and last access file times

if they are available.

Creation and last access columns are disabled by default and can be

enabled in “Select file list columns” dialog. This dialog is opened

after right clicking on file list column headers or after pressing

“File list/Files/Columns…” button in WinRAR settings.

4. “Double extensions for archives” and “Archives in subfolders”

options on “Files” page of archiving dialog modify behavior of

“Put each file to separate archive” option.

You can switch between archive names in filename.ext.rar

and filename.rar style with “Double extensions for archives”.

You can create a separate archive for every file in selected subfolders

or store the entire contents of every selected folder in separate

archive depending on the state of “Archives in subfolders” option.

5. New -ad1 switch can be used when unpacking multiple archives

recursively, such as ‘rar x -r -ad1 arc\*.rar’. It creates

a separate folder for files unpacked from each archive,

but unlike already existing -ad switch, it creates such folders

in each archive folder.

6. If context menu “Extract each archive to separate folder” is applied

to archives from different folders in?Windows?Explorer “Search results”,

subfolders with unpacked files are created in each archive folder.

Previous versions created them all in a folder of right clicked archive.

7. New “File list/List style/Checkboxes” option in WinRAR settings

allows to use checkboxes to select file list items.

8. New “File list/Files/Exact sizes” option in WinRAR settings.

If this option is on, file sizes are always displayed in bytes.

If it is off, sizes are rounded up and use units such as KB or MB.

Smaller files can be still displayed in bytes.

9. If several console RAR are started with -ioff switch, PC is turned off

by RAR copy finished last. Previously this switch was processed

by first finished copy.

10. Read and write buffer size is increased for .iso files.

It can help to improve .iso extraction performance in some cases,

such as for network drives.

11. If “Delete archive” option in extraction dialog is applied to a set

of RAR and REV volumes in volname.part# format, WinRAR will delete

REV volumes as well. Previously only RAR volumes were deleted

keeping REV files intact.

12. If “Delete archive” option in extraction dialog is applied to set

of ZIP volumes with .zip.001, .zip.002, .zip.003 extensions,

WinRAR will delete all ZIP volumes. Previously only .zip.001 volume

was deleted for such volume naming scheme.

13. If we unpack arcname.rar using “Extract to arcname\” Explorer context

menu command and “arcname” file already exists, WinRAR shell extension

will propose “Extract to arcname~1\” instead. Previously this context

menu command attempted to create a folder with same name as already

existing file and failed.

14. If we pack a shortcut file with .lnk extension from Explorer context

menu, .lnk file itself is added to archive. Previous versions added

.lnk file target instead of .lnk file.

15. Windows does not allow executables exceeding 4 GB, so WinRAR issues

an error immediately when attempting to create 4 GB or larger

RAR SFX volumes. Previously WinRAR issued such error only after

creating the first RAR volume.

16. Total extraction progress is displayed for 7z multivolume archives.

Accuracy of 7z total extraction progress is improved.

17. “Find” command “Disks and folders” drop down list has been renamed

to “Search area”. Additionally to already existing choices,

it includes a new “Selected items” option restricting search

to files and folders selected in WinRAR file list.

18. “Find” command displays the number of found items in status bar.

19. “Diagnostic messages” window displays archive names in a separate

column to provide the better message visibility for lengthy

archive names.

20. Switch -isnd[-] in command line WinRAR mode allows to override

“Enable sound” option in WinRAR settings. Use -isnd to turn sound

notifications on and -isnd- to turn them off.

21. Nadav Grossman from Check Point Software Technologies informed us

about a security vulnerability in UNACEV2.DLL library.

Aforementioned vulnerability makes possible to create files

in arbitrary folders inside or outside of destination folder

when unpacking ACE archives.

WinRAR used this third party library to unpack ACE archives.

UNACEV2.DLL had not been updated since 2005 and we do not have access

to its source code. So we decided to drop ACE archive format support

to protect security of WinRAR users.

We are thankful to Check Point Software Technologies for reporting

this issue.

22. Bugs fixed:

a) console RAR mixed up source and destination file sizes and times

in the overwrite prompt when updating a file in RAR archive

with -o switch;

b) dragging files from 32-bit applications to 64-bit WinRAR window

did not work;

c) WinRAR Shift+Del command applied to a folder could fail to delete

some its subfolders. This command is used to delete files and folders

permanently instead of moving them to Recycle Bin;

d) folder tree panel could not change folders if archived pathnames

started from path separator, such as in archives created by tar tool

with –absolute-names option;

e) if relative “Path=.\somefolder” was specified in SFX comment

and SFX archive needed to elevate privileges when extracting,

it created ‘somefolder\somefolder’ instead of ‘somefolder’;

f) commands modifying an existing RAR4 volume reset the volume number

field to 1. While it did not affect extraction, WinRAR displayed

a wrong volume number for such volumes;

g) fixed a crash when reading a comment from a corrupt RAR file;

h) toolbar in “Find” command “Search results” window was not adjusted

to different toolbar icon sizes properly.
