Anyone knows a simple JavaScript library implementing the UNZIP algorithm? No disk-file access, only zip and unzip a string of values. There are ActiveX, using WinZIP and other client dependent software for ZIP, written in JS. But no pure JavaScript algorithm implementation. I would use it for displaying KMZ files in a HTML page with the GMap object (google maps). The KMZ file is just a zipped KML

How do I unzip a .zip file in Goolge Cloud Storage Bucket? (If we have some other tool like 'CloudBerry Explorer' for AWS, that will be great.) Here is some code I created to run as a Firebase Cloud Function. It is designed to listen to files loaded into a bucket with the content-type 'application/zip' and extract them in place. const functions = require('firebase-functions'); const admin = require("firebase-admin"); const path = require('path'); const fs = require('fs'); const os = require('os'); const unzip = require('unzipper') admin.initializeApp(); const storage = admin.storage(); const

We are building a service for uploading zip-files containing an ESRI-shapefile. The service should be able to read the shapefile and do stuff with its content. So I've built a class that unzips the zip-file to temporary folder (subfolder of System.getProperty("java.io.tmpdir")). Another class calls the unzip method from the Unzip-class and it then tries to read the unpacked shapefile using Geotools. It uses the Geotools DataStoreFinder.getDataStore(Map params) method to create a datastore from the unzipped shapefile. Here the problem occurs: the getDataStore-method returns null. I tested the

I'd like to do something like this in my program: File zipFile = .....; File destDir = ....; ImaginaryZipUtility.unzipAllTo(zipFile, destdir); I cannot possibly be the first to do this from a program. Where do I find a utility method like above? I tried to look at apache commons-io, but nothing there. So, where should I look? jsshah Very old code that I was able to dig up package com.den.frontend; import java.util.*; import java.util.zip.*; import java.io.*; public class ZIPUtility { public static final int BUFFER_SIZE = 2048; //This function converts the zip file into uncompressed files which

I have noticed that the unzip facility in Java is extremely slow compared to using a native tool such as WinZip. Is there a third party library available for Java that is more efficient? Open Source is preferred. Edit Here is a speed comparison using the Java built-in solution vs 7zip. I added buffered input/output streams in my original solution (thanks Jim, this did make a big difference). Zip File size: 800K Java Solution: 2.7 seconds 7Zip solution: 204 ms Here is the modified code using the built-in Java decompression: /** Unpacks the give zip file using the built in Java facilities for
