Examples

robocopy c:\hope c:\hope2 *.txt

In this first example any .txt file would be copied from the hope directory into the hope2 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:\hope c:\hope2

In the above example the robocopy command would copy all files (not directories) in the hope directory to the hope2 directory.

robocopy c:\hope c:\hope2 /e

In the above example all files and folders (including empty ones) will be copied from the hope directory to the hope2 directory.

robocopy c:\hope c:\hope2 /MIR

This example will mirror what is in c:\hope into c:\hope2 and purge any files in the hope2 directory that do not exist in the hope directory. Use the /mir switch cautiously since it will be deleting files that do not match in the destination directory.

robocopy \\computer\hope C:\hope2

Next, this example would copy any of the files in the hope directory on the network computer named computer to the current computer hope2 directory.
