RAR is a private file format for file compression and archiving, which is used for data compression and archiving.

RAR was developed by Eugene Rochelle, and RAR's full name is "Roshal Archive", which means "Rochelle's Archive". The first public version of RAR was released in 1993, and he developed programs to compress or decompress RAR files, initially for DOS, and later ported to other platforms.

The main Windows version encoder, called Winrar, is released as shareware. However, Rochelle discloses the source code of the decoder, and the UNRAR decoder license allows conditional free distribution and modification on the condition that the compilation of RAR-compatible encoders is not allowed to be released, and RAR encoders have always been patented.

Considerations for compressing files

RAR is usually higher than a closed car zip compression ratio, but the compression decompression speed is slower. Volume compression: Splits the compression into multiple files.

Solid compression: Treat the file to be compressed as the same file to increase the compression ratio, at the cost of extracting any file in the package and decompressing the entire package. Recovery Records:

Redundant data is added for repair, and the corrupted package can be restored when the package itself is corrupted but there are enough recovery records. Previously, RAR's encryption algorithm was private. At present, none of them have been directly breached, and there is only brute force cracking when there is no password.

.RAR is a proprietary format used for compression and archivingThe use of RAR is very common, and it is often used to compress files and organize data. It is to save the original object data as a rar file format suffix after compression, usually Windows users are more common compression software winrar, by using winrar to compress the file data, the default file format is the rar format.

Advantages of RAR-specific formats:

1. Compared with the compressibility of ZIP, RAR has a much higher compression ratio than ZIP, and it is very portable. Moreover, RAR's secrecy attack core is also relatively good, and the security performance is also high.

2. RAR's segmentation effect is very good, it can not only divide the file compression target into multiple files, but also decompress the source file from the split file.

3. RAR can also support compressing all files to the same area to increase the compression ratio, and can repair information in RAR to ensure that even if the file is damaged, the information can be repaired in time.

RAR is a compressed file that needs to be compressed with a compression software, such as WinZip WinrarIt's something where multiple files are compressed together.

The exe is just like an app.

exe file executable A type of executable that can be floated in the storage space of the operating system. ms-dos and ms-windows, such file extensions are . exe

Binary executable files in the Windows operating system, executable files are divided into two types, one is the dropout name. com the other is. exe up.

COM is generally used for DOS, and the executable file in Windows is generally used. exe file.

In ms-dos, the file extension used to identify an executable file.

Name. The user enters without a . in the prompt lineexe extension.

Execute the program exe file structure.

The exe file is more complex, and each exe file has a file header, which is structured as follows:

The header of the exe file.

Similarly, RAR files are usually compressed more than zip files, but the compression speed is slower. Because the RAR file header also occupies a certain amount of space, when there is not much room for data compression, the compressed file may be larger than the original file. One of the main advantages of RAR is that it is possible to split the file compression target into multiple files, and it is easy to extract the source file from such a split compressed file.

In addition, RAR also supports the compression format, which compresses all files into the same data area to increase the compression ratio, at the cost of decompressing a single file and having to decompress all the files in front of it. The encryption algorithm of the new RAR uses AES, while the encryption algorithm of the old RAR is private. Both algorithms are difficult to crack, so they can only be cracked using dictionary brute force without a password.

Redundant repair information can also be added to the RAR, which can be used to repair the archive when the file is corrupted but the repair information is good enough.
