Copy files without permissions, cmd line or gui

Need to back-up laptop and desktop drives without file permissions getting in the way? 
1) Command Line - GUI tool see below

Use RoboCopy (Robust File Copy) a command-line file copying tool built into Windows. It is designed for high-speed multi-threaded reliable copying to target destination, especially with long and peculiar file names that Windows Explorer has trouble copying. 
This particularly useful when back-up from old drives to external USB drive, in this example. Additionally, you can specify that file permission NOT be included when copying the files over so, any computer that uses the external harddrive can see those files.

This command worked well for me.

  1. Restartable mode (/Z) has to do with a partially-copied file. With this option, should the copy be interrupted while any particular file is partially copied, the next execution of Robocopy can pick up where it left off rather than re-copying the entire file. That option could be useful when copying very large files over a potentially unstable connection.
  2. Backup mode (/B) has to do with how Robocopy reads files from the source system. It allows the copying of files on which you might otherwise get an access denied error on either the file itself or while trying to copy the file's attributes/permissions. You do need to be running Command Prompt or Poweshell as Administrator context or otherwise have backup rights to use this flag.

This command works well and the /B swicth ignores file permissions. Make sure you understand the other switches, see below.

RoboCopy Command Line Syntax:

RoboCopy has a handy command line progress indicator too which comes useful while copying large files and will indicate what and which files failed to copy. Summary is excellent as well.

Robocopy is built-in on the following Operating Systems: Windows 10, Windows 8, Windows 7, Windows Vista, Windows Server 2008 
Robocopy was available for free download with the Windows 2003 Resource Kit since Windows NT 4.0., Windows Server 2003, Windows XP, and Windows 2000 or Microsoft Windows NT version 4.0.

If you have a problem following command lines, then there's

2) RichCopy a utility with a GUI available from Microsoft MSDN Magazine.
This is an improvement and separate tool from Robocopy GUI.
Get RichCopy download  and the full MSDN Article about this is here. Help here.

RichCopy is a free utility that comes to us from Ken Tamaru of Microsoft. The tool was first developed in 2001. It too is multi-threaded will allow you to ignore file permissions.

Multi-threaded means that rather than copying one file at a time in serial order, RichCopy can open multiple threads simultaneously, allowing many files to be copied in parallel and cutting the total time required to complete the operation several times over. You can also pause and resume file copy operations, so if you lose network connectivity at any point, you can just pick up where you left off.

How to ignore file attributes (permissions) when copying
Firstly, choose Advanced

Choose Copy Options

Select 1) File attributes, Error Handling and then Unheck 2) File Attributes 

Additionally, you can select which File attributes to set or File Attributes to remove. The tool is very extensive!  Tool comes with help file, but for reference Online help is here.
