I have created a C# console program that do the job in very efficient way, even has a better performance from my above batch script.
i'm sharing it here in case anyone face this problem, can use this code:
*** envControl is text file path that contains the directories you want to perform extracting html from .zip operation. write every directory path in a separate line.
string envControl = @"C:\text.txt"
public void Unzip()
{
using (StreamReader sr = File.OpenText(envControl))
{
string s = String.Empty;
while ((s = sr.ReadLine()) != null)
{
string extractPath = s;
//+++++++++++++++++++++++++++++++++++++++++
string fileNameToDetele = "";
string[] files =
Directory.GetFiles(extractPath, "*.zip", SearchOption.TopDirectoryOnly);
foreach (var item in files)
{
fileNameToDetele = Path.GetFileNameWithoutExtension(item) + ".html";
if (File.Exists(extractPath + fileNameToDetele))
{
File.Delete(extractPath + fileNameToDetele);
}
RenameZipEntries(item);
System.IO.Compression.ZipFile.ExtractToDirectory(item, extractPath);
if (File.Exists(item))
{
File.Delete(item);
}
}
//+++++++++++++++++++++++++++++++++++++++++
}
}
}
private static void RenameZipEntries(string file)
{
using (var archive = new ZipArchive(File.Open(file, FileMode.Open, FileAccess.ReadWrite), ZipArchiveMode.Update))
{
var entries = archive.Entries.ToArray();
foreach (var entry in entries)
{
var newEntry = archive.CreateEntry(Path.GetFileNameWithoutExtension(file) + ".html");
using (var a = entry.Open())
using (var b = newEntry.Open())
a.CopyTo(b);
entry.Delete();
}
}
}
