RAR？ It is the native format of WinRAR decompression software. ? RAR？ A file is a data container that can store one or more files in compressed form, and its extension is. rar。 Compared with other available compression tools, RAR? Provides a number of advanced features, including multi-volume archiving, strict compression and record recovery.
function
1, fully supports the cases of RAR and ZIP compressed packages, and can extract CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO and 7z? And then what? ZIP compressed package shell.
2.AES can be used for 128-bit encryption.
3. The maximum file size is 8.589 billion TB.
4. You can make self-extracting files.
5. The data can be repaired.
6.WinRAR supports NTFS system and Unicode file names.
7.WinRAR can be tried for 40 days. A reminder window will pop up after the probation period, but it can still be compressed and decompressed.
8. The trial version cannot pass the certificate verification.

File characteristics
1 and RAR usually have higher compression ratio than ZIP, but the compression/decompression speed is slower.
2. Volume compression: divided into multiple files after compression.
3. Solid compression: treat the files to be compressed as the same file to improve the compression ratio, at the cost of extracting any file in the compressed package and decompressing the whole compressed package.
4. Recover records: add redundant data for repair. When the compressed package itself is damaged but there are enough recovery records, the damaged compressed package can be recovered.
5. encryption: RAR 2.0 uses AES-128-CBC (AES-256CBC after rar 5.0). Previously, RAR's encryption algorithm was confidential. At present, there is no effective cracking method except violent cracking (at least not open).
