Decompressing password-protected ZIP files with .NET 4.5
Unfortunately not. There is no support within the .Net Framework 4.5 for password protected zip files. In this case you have to switch to one of the well known 3rd party libraries.

To extract files from a .tar.gz file you can use the following methods from packages distributed with Ruby: require ‘rubygems/package’ require ‘zlib’ tar_extract = Gem::Package::TarReader.new(Zlib::GzipReader.open(‘Path/To/myfile.tar.gz’)) tar_extract.rewind # The extract has to be rewinded after every iteration tar_extract.each do |entry| puts entry.full_name puts entry.directory? puts entry.file? # puts entry.read end tar_extract.close Each entry of type Gem::Package::TarReader::Entry … Read more
Decide what classifier you will use for your zip file, for sake of argument let’s say it would be sample. In your project create file assembly/sample.xml Fill in assembly/sample.xml with something like this: <?xml version=”1.0″ encoding=”UTF-8″?> <assembly xmlns=”http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2″ xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xsi:schemaLocation=” http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd” > <id>sample</id> <formats> <format>zip</format> </formats> <fileSets> <fileSet> <outputDirectory>/</outputDirectory> <directory>some/directory/in/your/project</directory> </fileSet> </fileSets> <!– use … Read more
If you want to read a zipped or a tar.gz file into pandas dataframe, the read_csv methods includes this particular implementation. df = pd.read_csv(‘filename.zip’) Or the long form: df = pd.read_csv(‘filename.zip’, compression=’zip’, header=0, sep=’,’, quotechar=”””) Description of the compression argument from the docs: compression : {‘infer’, ‘gzip’, ‘bz2’, ‘zip’, ‘xz’, None}, default ‘infer’ For on-the-fly … Read more

This is how I installed it on my machine (ubuntu): php 7: sudo apt-get install php7.0-zip php 5: sudo apt-get install php5-zip Edit:Make sure to restart your server afterwards. sudo /etc/init.d/apache2 restart or sudo service nginx restart PS: If you are using centOS, please check above cweiske‘s answer But if you are using a Debian … Read more
you can take a look at ZipArchive, you would be able to create zips with that and let the user download it. Cletus provide a really good answer there. I humbly copy his sample here $files = array(‘readme.txt’, ‘test.html’, ‘image.gif’); $zip = new ZipArchive; $zip->open(‘file.zip’, ZipArchive::CREATE); foreach ($files as $file) { $zip->addFile($file); } $zip->close(); and … Read more
I suggest you have a look at ZipFile.entries(). Here’s some code: try (ZipFile zipFile = new ZipFile(“test.zip”)) { Enumeration<? extends ZipEntry> zipEntries = zipFile.entries(); while (zipEntries.hasMoreElements()) { String fileName = zipEntries.nextElement().getName(); System.out.println(fileName); } } If you’re using Java 8, you can avoid the use of the almost deprecated Enumeration class using ZipFile::stream as follows: zipFile.stream() … Read more
You can solve this a bit more generally with less code. Essentially, create enough of a file-like object for ZipFile to use. So you wind up with z = ZipFile(HttpFile(url)) and it dynamically downloads just the portion needed. The advantage with this is you write less code, and it applies to more than just zip … Read more
Check: http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=38&t=004618 I am not aware of any public API that will help you do that. (Although if you do not want to do it programatically, there are utilities like WinSplitter that will do it) I have not tried it but, every ZipEntry while using ZippedInput/OutputStream has a compressed size. You may get a rough … Read more
