Take a look at Libarchive. I spent a lot of time seeking for a cross-platform and LGPL licensed library with convenient interface. This the best of all I’ve seen. Very easy and powerful tool. Originally designed for Unix-like systems but there’s also the Windows version.
BytesIO() needs to be passed bytes data, but a ZipFile() object is not bytes-data; you actually created a file on your harddisk. You can create a ZipFile() in memory by using BytesIO() as the base: memory_file = BytesIO() with zipfile.ZipFile(memory_file, ‘w’) as zf: files = result[‘files’] for individualFile in files: data = zipfile.ZipInfo(individualFile[‘fileName’]) data.date_time = … Read more
Finally I got answer of my question: https://github.com/eligrey/Blob.js/ https://github.com/eligrey/FileSaver.js/ Here is the code: var xhr = new XMLHttpRequest(); xhr.open(“POST”, baseURLDownload + “/service/report/QCPReport”, true); xhr.setRequestHeader(“Content-type”,”application/json”); xhr.setRequestHeader(“Access-Control-Allow-Origin”, “*”); xhr.onreadystatechange = function() { if (xhr.readyState == 4 && xhr.status == 200) { // alert(“Failed to download:” + xhr.status + “—” + xhr.statusText); var blob = new Blob([xhr.response], {type: … Read more
With the release of the .NET Framework 4.5 this is actually a lot easier now with the updates to System.IO.Compression which adds the ZipFile class. There is a good walk-through on codeguru; however, the basics are in line with the following example: using System.Collections.Generic; using System.IO; using System.IO.Compression; using System.IO.Compression.FileSystem; namespace ZipFileCreator { public static … Read more
Welcome to Stack Overflow :). You are on the right way. Your real problem is using a zip. The following configuration is ok and work great for me. It’s an old one (2 years ago), and I’m not sure that match the best practices. But I Know that’s working. This allow me to share some … Read more
The zipfile.write() method takes an optional arcname argument that specifies what the name of the file should be inside the zipfile I think you need to do a modification for the destination, otherwise it will duplicate the directory. Use :arcname to avoid it. try like this: import os import zipfile def zip(src, dst): zf = … Read more
After a little more playing around and reading I was able to figure this out. Here is how you can create a zip file (archive) with multiple files without writing any temporary data to disk: using (var compressedFileStream = new MemoryStream()) { //Create an archive and store the stream in memory. using (var zipArchive = … Read more
If you don’t want to install anything but do want to download an SVN or GIT repository, then you can use this: http://downloadsvn.codeplex.com/ I have nothing to do with this project, but I just used it now and it saved me a few minutes. Maybe it will help someone.

As noted elsewhere in the comments, this will only work on a already-created Zip file. The content must also not already exist in the zip file, or an error will be displayed. Here is the working sample code I was able to create based on the accepted answer. You need to link to shell32.lib and … Read more
