Some of these utilities (such as robocopy and takeown) later shipped as part of Windows XP and Windows Vista.

RichCopy

Ken Tamaru of Microsoft has developed a copying program similar to Robocopy, called RichCopy, which is available on Microsoft TechNet.
Additionally, while having some similarities (like multithreaded copying) with the Microsoft utility, Robocopy, it provides a complete graphical user interface (GUI), whereas Robocopy is a command-line utility, although there are GUI interfaces for Robocopy.

XCOPY

Robocopy functionally replaces Xcopy, with more options. Robocopy syntax is markedly different from its predecessors (copy and xcopy), in that it accepts only folder names, without trailing backslash, as its source and destination arguments.

GS RichCopy 360

GS RichCopy 360 is a commercial alternative to Microsoft's Robocopy, included in Windows, and to the discontinued free RichCopy file copy utility.

* Copy directory recursively, copy all file information (, equivalent to, =Data, =Attributes, =Timestamps, =Security=NTFS ACLs, =Owner info, =Auditing info), do not retry locked files (the number of retries on failed copies default value is 1 million), preserve original directories' Timestamps ( - requires version XP026 or later):

Wildcard character

File names and wildcard characters (such as and ) are not valid as source or destination arguments; files may be selected or excluded using the optional "file" filtering argument (which supports wildcards) along with various other options.

Interpacket gap

Robocopy's "inter-packet gap" (IPG) option allows some control over the network bandwidth used in a session.

Data-rate units

Mbit/skbit/sGbit/s
In theory, the following formula expresses the delay (D, in milliseconds) required to simulate a desired bandwidth (B D, in kilobits per second), over a network link with an available bandwidth of B A kbps:

The methodology employed by the IPG option may not offer the same level of control provided by some other bandwidth throttling technologies, such as BITS (which is used by Windows Update and BranchCache).
