RAR is a private file format for file compression and archiving, used for data compression and archiving packaging. RAR usually has a higher compression ratio than ZIP, but the compression/decompression speed is slower; the file characteristics are: volume compression, solid compression, and can restore the damaged compressed package when the compressed package itself is damaged but there are enough recovery records.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
What is the format of RAR?
RAR is a private file format for file compression and archiving. It is used for data compression and archiving packaging. To put it simply, the original file data is compressed and saved as RAR.

The developer of RAR is Eugene Rochelle. The full name of RAR is "Roshal ARchive", which means "Roshal's Archive". RAR usually has a higher compression ratio than ZIP, but the compression/decompression speed is slower. The file features are volume compression and solid compression. When the compressed package itself is damaged but there are enough recovery records, the damaged compressed package can be restored.
RAR files have more redundant records, mainly because the compressed data is damaged during the compression process. In order to ensure lossless compression, there will be more recovery records, and these recovery records also occupy a certain amount of time. Space. However, volume compression is a very prominent advantage of RAR. It divides the source file into multiple small files, which is beneficial to decompressing the source file. If all data is compressed into the same data area, the compression ratio can be greatly increased. However, when decompressing a single file, this compression method must decompress all the files before it in the same data area, which is not conducive to Individual decompression of files.
