Sub folders are not copyied

Question

I am using the function on this SO post to copy folders content into another folder, but it's not copying the sub folders and their content.

private static void DirectoryCopy(string sourceDirName, string destDirName, bool copySubDirs)
{
    DirectoryInfo dir = new DirectoryInfo(sourceDirName);
    DirectoryInfo[] dirs = dir.GetDirectories();

    // If the source directory does not exist, throw an exception.
    if (!dir.Exists)
    {
        throw new DirectoryNotFoundException(
            "Source directory does not exist or could not be found: "
            + sourceDirName);
    }

    // If the destination directory does not exist, create it.
    if (!Directory.Exists(destDirName))
    {
        Debug.Log("Directory created.." + destDirName);
        Directory.CreateDirectory(destDirName);
    }

    // Get the file contents of the directory to copy.
    FileInfo[] files = dir.GetFiles();

    foreach (FileInfo file in files)
    {
        // Create the path to the new copy of the file.
        string temppath = Path.Combine(destDirName, file.Name);

        // Copy the file.
        file.CopyTo(temppath, false);
    }

    // If copySubDirs is true, copy the subdirectories.
    if (copySubDirs)
    {

        foreach (DirectoryInfo subdir in dirs)
        {
            // Create the subdirectory.
            string temppath = Path.Combine(destDirName, subdir.Name);

            // Copy the subdirectories.
            DirectoryCopy(subdir.FullName, temppath, copySubDirs);
        }
    }
}

This is how it's called:

string destingationPath = startupFolder + @"\NetworkingDemoPlayerWithNetworkAwareShooting1_Data";
DirectoryCopy("NetworkingDemoPlayerWithNetworkAwareShooting1_Data", destingationPath, true);

Your code worked perfectly fine for me... It copied all directories and sub directories. Could you please check the path in calling method once? — A3006, Oct 19 '16 at 11:47
I guess this exception hindering the copy IOException: Win32 IO returned 112. — Muhammad Faizan Khan, Oct 19 '16 at 11:56

I agree that your code looks correct

Windows system error 112 means there is not enough space on the disk

usually Windows system error 112 means there is not enough space on the disk – cristallo Oct 19 '16 at 12:03
update this thing in to your code so that i can accept it. Although my code is also valid. anyhow thanks again – Muhammad Faizan Khan Oct 19 '16 at 12:25
but why do my copied applicaiton not running. and giving me the error "C:\..... player.exe is not a valid win32 application" – Muhammad Faizan Khan Oct 19 '16 at 12:29
can you compare source and destination file? Are binary identical? – cristallo Oct 19 '16 at 12:34
exe file which i am copying is not full copied. it is actually 16 mb while it showing 16 kb only. File.Copy(ownPath, Path.Combine(startupFolder, "Player.exe")); – Muhammad Faizan Khan Oct 19 '16 at 12:52
I suggest you to use also the third parameter of the copy method, File.Copy(ownPath, Path.Combine(startupFolder, "Player.exe"), true) it enables the overwriting – cristallo Oct 19 '16 at 12:57
actually the problem is exe is open when its copying . – Muhammad Faizan Khan Oct 19 '16 at 13:00
generically speaking it should not be a problem, I am pretty confused – cristallo Oct 19 '16 at 13:05
so what to is the problem? I used this code to copy my exe into destination folder and it happen when application is running File.Copy(ownPath, Path.Combine(startupFolder, "Player.exe")); – Muhammad Faizan Khan Oct 20 '16 at 04:25
Did you try to use the overwriting flag? – cristallo Oct 20 '16 at 08:08
it could be related to the windows security system. can you verify if your exe file is blocked? see this article http://www.thewindowsclub.com/fix-windows-blocked-access-file – cristallo Oct 20 '16 at 08:09
