unzip

I have a zip folder on my SD card, how do i unzip the folder (within my application code) ? rich.e I am using a modified version of Beginner's method that extends AsyncTask and can update Observers on the main thread. Byte by byte compression is extremely slow and should be avoided. Instead a more efficient approach is to copy large chunks of data to the output stream. package com.blarg.webviewscroller; import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.util.Enumeration; import

Using python 2.4 and the built-in ZipFile library, I cannot read very large zip files (greater than 1 or 2 GB) because it wants to store the entire contents of the uncompressed file in memory. Is there another way to do this (either with a third-party library or some other hack), or must I "shell out" and unzip it that way (which isn't as cross-platform, obviously). Here's an outline of decompression of large files. import zipfile import zlib import os src = open( doc, "rb" ) zf = zipfile.ZipFile( src ) for m in zf.infolist(): # Examine the header print m.filename, m.header_offset, m.compress

I have zip file which contains some other zip files. For example, the mail file is abc.zip and it contains xyz.zip , class1.java , class2.java . And xyz.zip contains the file class3.java and class4.java . So I need to extract the zip file using Java to a folder that should contain class1.java , class2.java , class3.java and class4.java . NeilMonday Warning, the code here is ok for trusted zip files, there's no path validation before write which may lead to security vulnerability as described in zip-slip-vulnerability if you use it to deflate an uploaded zip file from unknown client.
