很多人愛用的WinRAR壓縮/解壓縮軟體最近推出了3.90 beta最新版，除了原本的32位元平台之外，還提供了64位元Windows系統的支援版本，讓WinRAR軟體在64位元系統提供比舊版更好的相容性與運作效能。目前新版程式只提供英文及德文兩種語言介面，由於台灣的代理商還滿認真的，應該不久後就會有中文版可以試用了，再等等囉。

3.90版在操作介面方面並沒有太大的變化，除了少部份的功能調整與BUG的修復之外，另外也改善在多核心CPU與多CPU環境的壓縮速度，在Windows Vista與Windows 7環境下應該可以感受到明顯的改進。不過，在最重要的Unicode支援的部份，還是只有部份支援，雖然可以正常解壓縮內含簡體中文、日文字的檔案名稱與資料夾名稱，不過如果直接用WinRAR開啟壓縮檔作編輯或修改，在回存檔案時還是會出現錯誤。

▇ 軟體小檔案 ▇     (錯誤、版本更新回報)

• 軟體名稱：WinRAR
• 軟體版本：3.90 beta 1
• 軟體語言：英文、德文（中文版稍等一陣子吧）
• 軟體性質：試用版軟體（全功能40天試用）
• 檔案大小：1.29MB
• 系統支援：Windows 98/2000/XP/2003/Vista
• 官方網站：http://rarlab.com/
• 軟體下載：32位元版本、64位元版本

新版WinRAR在多國語言方面的處理還是有點問題，目前測試，用WinRAR 3.90開啟內含日文或簡體中文檔名的檔案或資料夾時，會出現錯誤。

用另外一套壓縮軟體「7-ZIP」開啟內含日文或簡體中文檔名的檔案或資料夾時，則可正常顯示文字、正常回存檔案。

WinRAR 3.90 beta 1改版細節： （轉貼自官方網站）

•    1. WinRAR version for Windows x64 is available. If you use Windows x64, it is strongly recommended to install 64 bit WinRAR version. It provides a higher performance and better  shell integration than 32 bit version.
•    2. RAR compression speed is improved for multi-core and multi-CPU systems. This improvement is most noticeable in Windows Vista and Windows 7 operating systems.
•    3. “Remove duplicate folders from extraction path” option in “Settings/Compression” dialog is replaced by more universal “Remove redundant folders from extraction path” option.
        This option will eliminate redundant archive name based folders from extraction path if you unpack an archive with “Extract to DestName\” context menu command and if archive root folder contains only one folder and no files.
•    4. Changes in “Extraction path and options” dialog:
        a) “New folder” button creates a new subfolder in currently
            selected folder;
        b) F2 key renames a selected folder in the folders tree;
        c) F5 key updated the tree pane contents;
        d) Del key removes a selected folder in the folders tree.
•    5. You can enable “Show seconds” option in “Settings/File list”
        dialog if you wish to see seconds in file dates in file list
        in WinRAR shell.
•    6. “Where to check for SFX archives” options group
        in “Settings/Integration/Context menus items” dialog lets
        you to control processing of SFX archives in context menus.
        For example, if you frequently right click “.exe” files
        on slow network disks, you can turn off “Network disks” options
        to minimize the delay before displaying the context menu.
•    7. If you sort files by name in the file list in WinRAR shell,
        WinRAR will use the new logical file name sorting,
        same as in Windows Explorer, considering digits in file names
        by their numerical value. So files will be sorted as
        1.txt, 2.txt, 10.txt instead of previous 1.txt, 10.txt, 2.txt.
        This new sort behavior is available in Windows XP Service Pack 2
        and newer.
•    8. Ctrl+W key combination can be used to close the main WinRAR window
        also as WinRAR viewer windows. “View as Windows text” shortcut
        in WinRAR viewer changed from Ctrl+W to Ctrl+I.
•    9. New command line switch -r- disables recursion completely.
        So ‘rar a -r- arc dirname’ command will add only the empty
        dirname folder and ignore its contents. By default, if dirname
        does not include wildcards, RAR adds its contents even if
        -r switch is not specified.
•   10. If used when extracting, the new command line switch -ai forces
        RAR to ignore file attributes. When using this switch,
        extracted files will always have attributes assigned by
        operating system to a newly created file by default.
•   11. If output file name is not specified in “cw” command, console RAR
        will send comment data to stdout.
•   12. When compressing stdin data with -si[name] switch, RAR sets
        modification time of archived entry to current system time.
        Previous RAR versions did not fill this field, resulting in
        meaningless modification time for stdin.
•   13. Message displayed when you place the mouse cursor on WinRAR
        tray icon includes the archive name now. Previously only
        time left and total percent were displayed for archiving operations.
•   14. Bugs fixed:
        a) WinRAR could fail to open tar or tar.gz archive if such archive
           contained a file larger than 8 GB;
        b) WinRAR context menu did not work properly in Windows 7 beta
           if icons in context menus were enabled and user clicked
           a file inside of Windows 7 Library folder;
        c) previous WinRAR versions failed to rename files having 5 or more
           continuous spaces in the name. WinRAR shell does not display
           such spaces for safety reasons, because they can hide an actual
           file extension. But this security measure prevented the rename
           command to work properly.
