unzip compressed files

Believe that the vast majority of life Win7 system users often encounter compression or decompression files, compressed files can make our data occupy a smaller memory space. But sometimes we win7 the flagship version of the 32-bit system to extract the file, but encountered the problem of the RAR compressed file has b

Compressing data creating gzip filesLet's look at a slightly troublesome approach? 123456 stringio,gzip content = ' life are short. I use python ' zbuf = Stringio.stringio () zfile = gzip. Gzipfile (Mode = = 9 = zbuf) zfile.write (content) zfile.close () But in fact there is a quick package, do not use the Stringio module? 123 f =gzip.open(‘file.gz‘, ‘wb‘)f.write(content)f.close() Compress

The most basic principle of file compression:Example: string: String str = "AAAAABBBBCCCCDDDEEEFFFF"; Algorithm compression is: A5B4C4D3E3F4Package main;Import java.util.*;public class Test {public static void Main (String[]args) {String str = "AAAAABBBBCCCCDDDEEEFFFF";MapList reslist = new ArrayList ();for (int i = 0; I String temp = str.substring (i,i + 1);Integer Count =maps.get (temp);if (count = = null) {Count = 1;} else {count++;System.out.println (count);}Maps.put (temp, count);}For (Stri

Is there any way to download the files in the compressed package directly with PHP without pressure?

The tool used is the Lsar/unar tool provided by the Unarchiver project.The Unarchiver Project home: http://code.google.com/p/theunarchiver/Installation (12.04 and above):Code:sudo apt-get install UnarPlease refer to the following 12.04 or friends who wish to compile and install:viewtopic.php?f=35t=353426Use:Let's say the zip package that needs decompression is Foo.zipCode:Lsar Foo.zip #列出所有文件If the file name listed is already correctCode:Unar Foo.zip #解压所有文件If the file name listed is not correct

Simple decompression of 7z files using the Lzma SDKsometimes we only need to extract the LZMA algorithm compressed 7z files, sometimes need to extract on the embedded devices, using P7zip although supporting a variety of formats, but not easy to crop, using the LZMA SDK is preferred:You can find various versions here: http://zh.sourceforge.jp/projects/sfnet_seven

relatively small, for example, only 2GB, compressed sleep files can make space is also very limited, at the expense of stability at the expense of a little space is not worth it. Small tip: If you encounter the above blue screen error after the modification, you can reboot the system into the Maintenance Command window and set a larger compression rate. If the problem persists, try executing the "powercf

This article illustrates how the Android programming implementation will copy compressed database files to the installation directory.
