Robocopy examples

robocopy c:\test c:\test2 *.txt
In this first example, any .txt file would be copied from the test directory into the test2 directory. Whenever you want to copy one or more files and not a complete directory the file must be specified after the destination directory.
robocopy c:\test c:\test2
In the above example, the robocopy command would copy all files (not directories) in the test directory to the test2 directory.
robocopy c:\test c:\test2 /e
In the above example, all files and folders (including empty ones) will be copied from the test directory to the test2 directory.
robocopy c:\test c:\test2 /MIR
This example will mirror what is in c:\hope into c:\test2 and purge any files in the test2 directory that do not exist in the test directory. Use the /mir switch cautiously since it is deleting files that do not match in the destination directory.
robocopy \\mypc\test C:\test2
Next, this example would copy any of the files in the test directory on the network computer named mypc to the current computer test2 directory.
