Robocopy, short for Robust File Copy, is a command-line directory replication and file copy command utility that was first made available as feature in Windows Vista and Windows Server , although it has been available as part of Windows Resources Kit.
In Windows 7 and Windows Server , Robocopy utility is further enhanced with ability to multi-threaded copy operation feature. Multi-threaded support allows Robocopy to open multiple threads simultaneously, allowing many files to be copied in parallel. With multi-threaded copying, total time required to complete the operation will be drastically reduced and cut, when comparing with with typical copying one file at time in serial sequential order. As Robocopy is generally a command-line only utility although a GUI add-on is available for Robocopy , the new multi-threaded operation capability has to be called via a new switch supported by Robocopy.
The new multi-threaded copy feature can be enabled and turned on with the following parameter:. Where n will instruct Robocopy to do multi-threaded copies with n threads default 8. The value of n must be at least 1 and not greater than between 1 to , with 1 as single thread.
In fact, Robocopy will copy files and folders in multi-threaded operation by default, with 8 threads in one go. To copy a directory without bandwidth limitation and logging with bytes level and ETA. Excludes files that match the specified names or paths. Specifies the wait time between retries, in seconds.
The default value of N is 30 wait time 30 seconds. Office Office Exchange Server. Not an IT pro? United States English. Post an article. Subscribe to Article RSS.

Sometimes we may need to move files. This can be done with robocopy too. While doing copy and move operations we can also need some logs, especially in bulk data operations.
In this example, we will write robocopy operation log to log file named backup. This will prevent regular output. Files and folders may have different properties. These properties can be used for different purposes like the listing owner, audit information, timestamps, etc.
