What's the difference between compressed file format rar and zip?

Rar and zip are both common compression formats, and many friends use them when compressing files, but what's the difference between them? We don't know how to choose when compressing, and we don't know which is better. Bian Xiao will now introduce the differences and comparisons between rar and zip in detail. Friends in need come and have a look.

What's the difference between compressed file format rar and zip?

The specific comparison is as follows:

1. Different compression algorithms

Rar format can provide better compression ratio. Zip is an open compressed file, and there is not only one algorithm. The advantage of zip is its high compression speed. Moreover, the rar format is private and has been patented. zip is open and free.

2. Different recovery records

Rar does not support the recovery of records, but zip supports the recovery of physically damaged data, and can also lock important compressed files.

3. Different size restrictions

There is almost no limit to the file size that rar can manage, while the maximum size of a single file that zip can handle is 4GB.

summary

The format of rar file is better, and the compression ratio of rar is obviously higher than that of zip, which is equivalent to 7z. But both are lossless data compression. The compression ratio of RAR files is usually higher than that of ZIP files, but the compression speed is slower. Because the RAR file header also occupies a certain space, when the space for data compression is small, the compressed file may be larger than the original file. One of the main advantages of RAR is that the file compression target can be divided into multiple files, and it is easy to extract the source files from the compressed files thus divided.

The above is the difference between the compressed file formats rar and zip brought by Bian Xiao. I hope I can help you.
