Import a shell method to copy file from one location to another,delete file,copy file and rename files and folders.
[DllImport("shell32.dll", CharSet = CharSet.Auto)]
public static extern int SHFileOperation(ref SHFILEOPSTRUCT FileOp);

Import a shell method to create a new directory.
[DllImport("shell32.dll")]
public static extern int SHCreateDirectoryEx(IntPtr hwnd, string pszPath, IntPtr psa);

To create a new folder :
private const string NULL_STRING = "\0";
newFolderPath is the path where you want to create your directory.
SHCreateDirectoryEx(this.Handle, newFolderPath + NULL_STRING, IntPtr.Zero);

To do all the file operation like move , copy ,delete and rename :-
public bool FileOperation(string sourceFileName, string destinationFileName, FileOp fileOp)
{
bool success = true;
try
{
SHFILEOPSTRUCT shf = new SHFILEOPSTRUCT();
shf.wFunc = (int)fileOp;
shf.fFlags = (short)FileOpFlags.AllowUndo | (short)FileOpFlags.NoConfirmation;
if(!string.IsNullOrEmpty(sourceFileName))
{
shf.pFrom = sourceFileName + NULL_STRING;
}
if(!string.IsNullOrEmpty(destinationFileName))
{
shf.pTo = destinationFileName + NULL_STRING;
}
int result = SHFileOperation(ref shf);

if (result != 0)
{
success = false;
}
}
catch (Exception exception)
{
MessageBox.Show(exception.Message, Application.ProductName, MessageBoxButtons.OK);
}
return success;
}

How to call this method :-
To Delete the file or folder.
FileOperation(newFolderPath, string.Empty, FileOp.Delete);

To Copy the File or Folder.
FileOperation(sourcePath, destinationPath, FileOp.Move);

To Rename the file or Folder.
FileOperation(sourcePath, destinationPath, FileOp.Rename);
