你從網路下載了一個壓縮檔,雙擊卻跳出錯誤訊息,或是解壓到一半就中斷。你只是想打開裡面的檔案,不是想研究壓縮技術,但偏偏在這一步卡住。如果你的電腦是比較舊的 32 位元 Windows 系統,很多新軟體已經不支援,連找個能用的解壓縮工具都變得困難。
一般人遇到這種狀況,會先想到用系統內建功能或免費軟體,但舊系統的支援往往被新版本放棄,介面也可能全是英文或簡體中文,看得一頭霧水。這類工具的切入點,其實是提供一個在舊電腦上依然能開啟、能解壓、能處理損壞檔案的基本方案,讓你不用為了開一個壓縮檔而被迫升級硬體或作業系統。
01WinRAR 32位元版跟一般版有什麼不同?
這個版本是專門給 32 位元 Windows 系統使用的,支援 Windows XP 到 Windows 10。如果你的電腦是 32 位元系統,安裝這個版本才能正常運作。它具備完整功能,包含建立 RAR 和 ZIP 壓縮檔、解壓縮多種格式、AES 加密、分割壓縮檔、修復損壞檔案等,不是精簡版。
02這套軟體可以解開哪些壓縮格式?
除了自家的 RAR 和 ZIP,它還能解壓 CAB、ARJ、LZH、TAR、GZ、ACE、UUE、BZ2、JAR、ISO、Z、7-Zip 等格式。也就是說,從網路下載的各種常見壓縮檔,它大多能處理。但要注意,建立壓縮檔只支援 RAR 和 ZIP 兩種格式。
03壓縮檔損壞了還有救嗎?
如果壓縮檔在建立時有加入恢復記錄(recovery record),WinRAR 就能嘗試修復損壞的檔案。它會用恢復記錄來重建損壞的資料,提高解壓成功的機會。但如果當初建立時沒有加恢復記錄,修復的成功率就會低很多,這點要先有心理準備。
04它能不能把大檔案分割成多個小檔?
可以。WinRAR 支援建立多卷分割壓縮檔,你可以把一個大檔案切成多個小部分,方便存到隨身碟或透過網路傳送。之後要還原時,只要把全部檔案放在同一個資料夾,對第一個分割檔執行解壓縮,它就會自動合併還原。
05可以幫壓縮檔設定密碼嗎?
可以,它提供 AES 加密,建立壓縮檔時可以設定密碼保護。這樣一來,只有知道密碼的人才能開啟或解壓縮內容。加密強度是 AES-256,這在目前算是常見的安全等級,適合用來保護敏感資料。
06這套軟體適合什麼樣的人用?
適合還在用 32 位元舊電腦、系統停留在 Windows XP 到 Windows 10 之間的使用者。另外,如果你需要建立 RAR 格式的壓縮檔,或經常遇到損壞的壓縮檔需要修復,它也是少數具備這些功能的工具。對一般只偶爾解壓縮的人來說,功能可能超出需求。
07它跟 7-Zip 比起來,選哪個比較好?
7-Zip 是免費開源軟體,支援的格式也很多,但無法建立 RAR 格式的壓縮檔。WinRAR 是唯一能建立原生 RAR 檔的軟體,而且有修復損壞檔案的功能。如果你只是要解壓縮,7-Zip 就夠用;如果你需要建立 RAR 檔或修復損壞壓縮檔,WinRAR 才有優勢。
08這套軟體是免費的嗎?
不是,它是共享軟體(shareware),提供 40 天試用期。試用期過後軟體還是能繼續使用,但會不定期跳出授權提醒。付費購買後,該版本可以終身使用。如果是公司或組織使用,官方要求必須購買授權,這點要注意。
09介面只有英文,會不會很難操作?
官方資料顯示它支援超過 50 種語言,但這個 32 位元版本的介面語系是英文。對不熟悉英文介面的人來說,剛開始可能需要花點時間摸索。不過解壓縮的基本操作很直覺,右鍵選單也會整合到 Windows 殼層,常用的「解壓縮到這裡」等功能可以從右鍵選單直接執行。
10什麼情況下不該選這套軟體?
如果你的系統是 64 位元,或已經升級到 Windows 11,這個 32 位元版本就不是為你的系統設計的,應該找 64 位元版本或其他工具。另外,如果你完全不想付費、也不需要用 RAR 格式或修復功能,免費的 7-Zip 或 PeaZip 就足夠,不需要選它。
11它跟 Bandizip 或 PowerArchiver 比起來如何?
這幾套都是壓縮工具,但定位不同。Bandizip 主打輕量、操作簡單,PowerArchiver 則有較多進階功能。WinRAR 的優勢在於 RAR 格式的建立與修復能力,以及長期的更新維護。不過 Bandizip 和 PowerArchiver 的評分人數都遠少於 WinRAR,使用經驗的參考樣本較少。
12這套軟體還有人在維護嗎?
有,它持續有更新,包含安全性修正和效能改善。根據收錄的版本紀錄,近 12 個月內有釋出更新,不是放著不管的軟體。對於還在用舊系統的人來說,持續更新代表安全性漏洞有在處理,這點相對重要。

這一版改了什麼
What's new in this version:
* RAR decompression speed is improved. Depending on data type, decompression can be up to 30% faster than in previous versions.
Both the general RAR algorithm and most of special RAR multimedia methods benefit from this improvement. The only module of RAR algorithm, which is not affected, is "Text compression" method.
* Changes in ISO support:
- UDF support is upgraded to UDF 2.50 revision. It makes possible to unpack most of Blu-ray ISO files;
- when browsing UDF ISO file, UDF revision number is displayed after the "UDF" format name in WinRAR address bar and in archive information dialog;
- WinRAR sets the folder modification date when unpacking folders stored in UDF and ISO9660 files.
* Changes in password dialog:
- WinRAR uses the same format of password dialog both when archiving and extracting, so "Show password" option is available also when extracting;
- "Organize passwords..." button in password dialog provides access to password organizer interface, where you can specify your frequently used passwords. You will be able to access these saved passwords using the drop down list or autocomplete feature in password dialog.
It is important to know that saved passwords are not encrypted and anybody having access to your computer can view them. Use "Organize passwords" feature only if your computer is protected from unauthorized access;
- "Use for all archives" option is available in password dialog when unpacking several archives at once. You can utilize it to apply an entered password to all archives.
If you use this option with an empty password, WinRAR will skip all encrypted archives;
- Unlike previous versions, the password from default compression profile is not used for extraction.
If you wish to use the same password for all extracting archives, press "Organize passwords..." button in the password dialog and define a new password entry, specifying "*" file mask in "Select for archives" field.
* In Windows 7 WinRAR will display the total operation progress also on WinRAR icon on Windows taskbar. You can disable it using "Taskbar progress bar" option on "General" page of WinRAR settings.
* Numerous Unicode support improvements allow to process non-English file names more smoothly. These improvements include:
- better Unicode handling in WinRAR in "Rename", "Convert", "Find" and other commands, in folder tree panel, in password request dialog and in many other parts of WinRAR interface;
- correctly displayed Unicode names in WinRAR items in Explorer context menus;
- Unicode support in .lng files, making WinRAR localization possible for Unicode only languages.
* Changes in -x switch syntax. Now you can specify a wildcard exclusion mask for folders. Such mask must have the trailing '' character, like -x*tmp* or -x* emp
* New "Extract relative paths" option in "Advanced" part of extraction dialog. If you browse some archive subfolder in WinRAR shell and enable "Extract relative paths" option, the path part up to and including the current subfolder will be removed from extracted file paths.
For example, if you are inside of "BackupMyData" archive folder and extract "Images" folder, it will be extracted as "Images", not as "BackupMyDataImages".
This option is the new default extraction mode, but you can change the default back to WinRAR 3.x style. Just select "Extract full paths" and then press "Save settings" in "General" part of extraction dialog.
* Windows 98, Windows Me and Windows NT are not supported by WinRAR and WinRAR self-extracting modules anymore. Minimum Windows version required for WinRAR 4.0 is Windows 2000.
If you need to run WinRAR on older Windows, you can download previous WinRAR versions from ftp://ftp.rarlab.com/rar
* If TAR, TAR.GZ or TAR.BZ2 archive contains symbolic or hard links and if destination file system is NTFS, WinRAR will create these links when unpacking such archive. WinRAR will create symbolic links as symbolic and hard links as hard in Windows Vista and newer and it will create all links as hard in older Windows.
If destination file system is FAT32 or any other not supporting file links, WinRAR will skip links when unpacking TAR, TAR.GZ and TAR.BZ2 archives.
* Recovery volume processing involves less disk seek operations resulting in higher performance.
* You can select Windows 7 library in tree panel in extraction dialog and WinRAR will use its default save location as the destination path.
* "Report" command allows to select HTML, Unicode text and usual text as output format for report file. Unlike previous WinRAR versions, now WinRAR preservers Unicode characters in reports when using HTML or Unicode text format. So non-English characters in file names will be displayed properly in such reports.
* Message list in GUI SFX archives displays only operation status and error messages. It does not contain names of all extracted files anymore. This change improves the speed and reduces memory requirements for SFX archives containing a large number of files. Also it makes easier to locate error messages, because they are not hidden among extracted file names.
* GUI SFX archives display "Extract" button instead of "Install" if no "Setup" or "Presetup" commands are present in the archive comment. If you prefer "Install" button, but do not need to execute any setup programs, you can add "Setup=<>" command.
* WinRAR displays the current percent above the operation progress bar when repairing an archive containing the recovery record and when processing recovery volumes.
* WinRAR limits the maximum possible volume size to 4 GB minus 1 byte when creating RAR volumes on a disk with FAT or FAT32 file system in volume size autodetecting mode. These file systems do not support 4 GB and larger files.
* If "Wait if other WinRAR copies are active" option is enabled and WinRAR waits for another copy, you can press "Continue" button in command progress window to force WinRAR to stop waiting. So now "Continue" button allows to override the state of "Wait if other WinRAR copies are active" option for current operation.
* WinRAR displays one password request instead of two, when saving an encrypted file back to RAR or ZIP archive after modifying it in some external editor. Previous WinRAR versions usually requested the password twice, both when extracting the original file and archiving its modified copy. Only RAR archives with encrypted file names were processed with the single password prompt.
* New error code 10 ("no files") is added to list of error codes returned in command line mode by RAR and WinRAR. This new code can be returned by archive, extract, delete and repair commands. It means that RAR did not find any files matched the specified file or archive mask.
* File name area in file overwrite dialog occupies several lines now. It makes possible to display much longer names.
* Now switch -ep3 converts not only disk letters, but also UNC paths. So \servershare will be converted to __servershare when archiving and restored to the original \servershare when extracting with -ep3.
* New "Background extraction" option in "Advanced" part of extraction dialog places WinRAR into background, when extracting files. You can save its default state with "Save settings" button in "General" part of extraction dialog, just like for other extraction options.
"Background archiving" option from the default compression profile does not affect the extraction behavior anymore.
* "Mode..." button in operation progress window is enabled also when extracting or testing archives. It provides access to "Command parameters" dialog, where you can set "Turn PC off when done" option for extraction and test operations.
Previously this dialog was accessible only when archiving.
* Bugs fixed:
- renaming a file in archive could also rename all other files with the same name in other folders of the same archive;
- previous versions displayed the wrong total packed size in "Info" command for multivolume CAB archives;
- in ZIP archives 'U' (update) and 'F' (fresh) commands could erroneously update even files not specified in the command line. It happened only for files in current folder which names matched files in ZIP archive. This bug was not present in usual 'A' (add) archiving mode.
Both the general RAR algorithm and most of special RAR multimedia methods benefit from this improvement. The only module of RAR algorithm, which is not affected, is "Text compression" method.
