NET under the open source compressed file operations component. Unlike the above 2, he supports more formats, such as Rar,zip,tar,7zip and so on. This open source project seems to have started last year and has evolved from several other open source projects, including the Dotnetzip,nunrar project. Of course, RAR is also ju

I. Common compression commands　In Linux, the zip file has the following extension:Gz:gzip compressionBZ2:BZIP2 compression.Tar.:tar program packaged data, no compressionTar.gz:tar is packaged and compressed by gzip.Tar.bz2:tar packaged and compressed by bzip2(Note that the extensions in Linux are not related to file attributes, just to keep us in mind.)BZIP2 is better than gzip compression, these two

First, the question of the proposed With the development of the Internet, the number of Web sites increased by an astonishing number. The role of the site in addition to the vast numbers of users to provide information services, but also should become netizens to upload and download the file site. In the process of uploading and downloading files, transmission time is the key, which requires a faster transmission speed. In the transmission speed fixed or up or down changes in the case, as far as

computer world. For a few years he suffered from alcohol abuse and his life began to break down in the late 1990s s. He was arrested several times for drunk driving or other illegal activities. Katz was found to have died in a hotel room in April 14, 2000, aged 37. The cause of death was alcohol-caused serious pancreatic bleeding, followed by a pile of empty bottles.Some existing archive Software Zip and other deflate-based formats were dominant until the middle of 1990s, and some new improved

BackgroundAs the company's CMS system, only accept files compressed in RAR format, so it is impossible to directly use the ZIP compression components provided in the Nodejs. Only from the WinRAR software to start, but there is not much on the internet related things, so the following is also trying to do.A few of the main problems solvedProblem of location acquisition of RAR SoftwareThrough node's command-l

Before introducing image compression encoding, consider the following question: why compression? You don't need to answer this question. Because the amount of data in the image information is amazing. For example, we can see that the data volume of an A4 (210mm * 297mm) image scanned with a medium-resolution (300 dpi) Scanner Based on the actual color? Let's calculate: there are a total of (300*210/25 .4) *

One, what is gzip gzip is a data format that, by default, compresses the data section using only the deflate algorithm; Gzip is a popular file compression algorithm and is now widely used, especially on Linux platforms. When applying gzip compression to a plain text file, the effect is very noticeable and can reduce file size by more than 70%. This depends on the content in the file. Using the GZIP modul
