Win 7 Robocopy
Robocopy is designed to work with two directories (folders) at a time, and the file specification is a secondary parameter. In addition, there are dozens of options that can be specified as command-line switches. The basic syntax is as follows:
robocopy source destination [file [file]...] [options]
The source and destination parameters are specified as drive:\path or \\server\share\path. The file parameter can contain one or more literal file names, or it can use the familiar ? and * wildcards. Available options include dozens of switches that control copying, file selection, retry options, and the ability to create log files. For instance, this command copies the contents of one folder and all its subfolders from a local drive E to a shared folder on a Windows Home Server:
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.)
To see the full syntax, type robocopy /? at a command prompt.
