WinRAR is a paid compression software. Many friends mistakenly think that this software is included by Microsoft because it is pre-installed on many ghost systems with a cracked version. In fact, it has nothing to do with Microsoft and has always been a paid compression software. However, good news is that the personal version of WinRAR is now completely free to download and use. If you are used to using WinRAR, you can give it a try.

WinRAR's latest features:

• Changes in compression algorithm: The maximum compression dictionary in 64-bit WinRAR has been increased to 1GB. The 32-bit WinRAR version can use a 256MB dictionary when creating compressed files.
• RAR 5.21 compression file format: Please refer to the "Configuration Settings" section in the WinRAR Help File for more detailed information on the "WinRAR.ini file".
• Removed feature: The reliability of the authentication feature did not meet the required level and has been removed.
• XZ compression file format: Added support for decompressing XZ compression file format.
• Changes in encryption algorithm: The encryption algorithm in CBC mode has been changed from AES-128 to AES-256. The key derivation function is based on PBKDF2 using HMAC-SHA256.
• Changes in compression file format: File time is now stored as Coordinated Universal Time (UTC) instead of the previous local time, making file communication in different time zones more intuitive.

Software downloads:

• 32-bit Chinese personal free version
• 64-bit Chinese personal free version

However, some netizens complained that although the Chinese personal version is completely free, it includes annoying pop-up ads. It seems that you can't have both fish and bear's paw. If you don't like pop-up ads, it is recommended to use the WinRAR 4.20 Simplified Chinese Special Edition. Don't tell others about it.
