I'm using the following code on Mac using Mono to unzip a zip file. The zip file contains entries under directories (for example foo/bar.txt). However, in the unzipped directory, instead of creating a directory foo with a file bar.txt, FastZip creates a file foo\bar.txt. How do I get around this?
FastZip fz = new FastZip();
string filePath = @"path\to\myfile.zip";
fz.ExtractZip(filePath, @"path\to\unzip\to", null);
This creates a file foo\bar.txt in path\to\unzip\to.
Apparently cannot use FastZip for this case so I ended up writing my own unzipping mechanism:
string filePath = @"path\to\myfile.zip";
string unzipDir = @"path\to\unzip\to";
using (var zipFile = new ZipFile(filePath))
{
foreach (var zipEntry in zipFile.OfType<ZipEntry>())
{
var unzipPath = Path.Combine(unzipDir, zipEntry.Name);
var directoryPath = Path.GetDirectoryName(unzipPath);
// create directory if needed
if (directoryPath.Length > 0)
{
Directory.CreateDirectory(directoryPath);
}
// unzip the file
var zipStream = zipFile.GetInputStream(zipEntry);
var buffer = new byte[4096];
using (var unzippedFileStream = File.Create(unzipPath))
{
StreamUtils.Copy(zipStream, unzippedFileStream, buffer);
}
}
}
use a forward slash to separate folders when creating the zip
