Copy all content from the folder into two file destination folder

Question

I want to copy all the content in a folder into two file destination folder.

   foreach (string newPath in Directory.GetFiles(@"E:\autotransfer", "*.*",
            SearchOption.AllDirectories))
            File.Copy(newPath, newPath.Replace(@"E:\autotransfer", 
   @"E:\autotransferbackup"), true);

   foreach (string newPath in Directory.GetFiles(@"E:\autotransfer", "*.*",
            SearchOption.AllDirectories))
            File.Copy(newPath, newPath.Replace(@"E:\autotransfer", 
   @"E:\autotransferbackupcp"), true);

Please be more specific. Other than the fact that using `string.Replace()` to manipulate file paths is not a great idea, the little bit of code you posted seems like it would work. Or at least do _something_. You say it _"doesn't work"_. In what way, _specifically_, does the code not work? Provide a good [mcve] that reliably reproduces your problem, and explain _precisely_ what that code does, and what you want it to do instead. (Note that the casing of the path returned by `GetFiles()` might not match the casing in your `Replace()` call.) — Peter Duniho, May 27 '17 at 07:38

You can use this code, for more information see the answer here: Copy all files in directory

    void Copy(string sourceDir, string targetDir)
    {
        Directory.CreateDirectory(targetDir);

        foreach (var file in Directory.GetFiles(sourceDir))
            File.Copy(file, Path.Combine(targetDir, Path.GetFileName(file)));

        foreach (var directory in Directory.GetDirectories(sourceDir))
            Copy(directory, Path.Combine(targetDir, Path.GetFileName(directory)));
    }

    private void button1_Click(object sender, EventArgs e)
    {
        Copy("E:\autotransfer", "E:\autotransferbackup");
        Copy("E:\autotransfer", "E:\autotransferbackupcp");
    }

If the directory structure is not the same, then you will need to check if the folder exists, if not, create it first, then copy the files.

Thank you sir.It works.My next problem is how it will auto transfer in every time that the folder autotransfer have a content and it will automatically sent to two directory. For I am a beginner of programming I need some help. Thank you sir. – Sam May 27 '17 at 09:13
What if I want to copy only the content of the two sub folders in the certain directory, how would it be. – Sam Jun 07 '17 at 01:02

Taken from here on msdn: https://msdn.microsoft.com/en-us/library/bb762914(v=vs.110).aspx

You can copy this function and use it in your code.

Hope this helps.

using System;
using System.IO;

class DirectoryCopyExample
{
    static void Main()
    {
        // Copy from the current directory, include subdirectories.
        DirectoryCopy(".", @".\temp", true);
    }

    private static void DirectoryCopy(string sourceDirName, string destDirName, bool copySubDirs)
    {
        // Get the subdirectories for the specified directory.
        DirectoryInfo dir = new DirectoryInfo(sourceDirName);

        if (!dir.Exists)
        {
            throw new DirectoryNotFoundException(
                "Source directory does not exist or could not be found: "
                + sourceDirName);
        }

        DirectoryInfo[] dirs = dir.GetDirectories();
        // If the destination directory doesn't exist, create it.
        if (!Directory.Exists(destDirName))
        {
            Directory.CreateDirectory(destDirName);
        }

        // Get the files in the directory and copy them to the new location.
        FileInfo[] files = dir.GetFiles();
        foreach (FileInfo file in files)
        {
            string temppath = Path.Combine(destDirName, file.Name);
            file.CopyTo(temppath, false);
        }

        // If copying subdirectories, copy them and their contents to new location.
        if (copySubDirs)
        {
            foreach (DirectoryInfo subdir in dirs)
            {
                string temppath = Path.Combine(destDirName, subdir.Name);
                DirectoryCopy(subdir.FullName, temppath, copySubDirs);
            }
        }
    }
}

Thank you for your response. I tried first the 1st suggestion/answer above and it works for me. Maybe for other situations I will try your code sir. Thank you sir. — Sam, May 27 '17 at 09:15
