Manual
Xcopy is a powerful version of the copy command with additional features; has the capability of moving files, directories, and even whole drives from one location to another.
Examples
xcopy c:\temp /e
The above example is the basic xcopy command to copy the files, directories, and subdirectories to the directory you’re currently in (directory yg sedang dipakai/aktif).
xcopy “c:\documents and settings\hope” /e
xcopy h:\*.* /a /e /k
xcopy a: b: /s /e /h
xcopy \rawdata \reports /d:12-29-1993
xcopy \rawdata \reports /d:12-29-1993 /l > xcopy.out
Alternatif for Windows 7 : Robocopy
robocopy source destination [file [file]…] [options]
robocopy “E:\test” \\server\public\test\ /MIR /W:20 /R:15 /LOG: \\server\public\logs
The /MIR switch tells Robocopy you want to mirror the two folders, copying all folders (even empty ones) from the source directory and purging folders from the destination if they no longer exist on the source. The /W and /R switches set the wait and retry options; in this case, Robocopy will retry each copy up to 15 times, waiting 20 seconds between attempts. (The defaults allow 1 million retries, at 30-second intervals, allowing copy operations to complete when an open file is closed, even if hours or days have passed since the command was first launched.)
Perform Multithreaded File Copies with Robocopy in Windows 7
To perform a multi-threaded copy, you use the new /MT[:n] switch, where n indicates the number of threads to be used. By default, n is 8 when you use the /MT option, and can be any value from 1 to 128.
Note that the multi-threaded option is not compatible with the /IPG and /EFSRAW options.
