Description:
------------
When I ran a script it chopped the "\" plus the first letter of a directory when processing some copy commands.  I looked at the script, and I think maybe the problem had something to do with the "explode" function.  I apologize for not being able to be more certain of this, but I am not a coder.

Reproduce code:
---------------
		// create dirs for processing the file (server)
		if ( $this->move_method == 'copy')
		{
			$dir_path = '' ;
			$splitarray = explode('/', $copy_path) ;
			for ($idir=0; $idir<count($splitarray); $idir++)
			{
				$dir_path .= trim($splitarray[$idir]) ;
				// don't bother making ../  ;-)
				if ($splitarray[$idir] == '..')
				{
					// do nothing
				}
				else if (!file_exists($dir_path))
				{
					// use the mkdir command
					mkdir($dir_path, 0777);
					chmod($dir_path, 0777);
				}

				$dir_path .= '/' ;
			}
		}

Expected result:
----------------
It is supposed to copy a file from "directoryX" to "directoryY\newlocation".

Actual result:
--------------
An error because it actually tries to copy the file from "directoryX" to "directoryYewlocation".
