Using Robocopy to Mirror Directories

by Barry Dysert
(last updated August 11, 2014)

Robocopy is the tool to use when working with entire directories, since that's what it was designed to do. Let's say you want to "mirror" directories, i.e., make two directory trees contain identical files/folders. This is similar to using the /E switch (which is covered under the tip titled "Using Robocopy to Copy Entire Directories") along with the /PURGE switch. (The /PURGE switch tells Robocopy to delete destination files/folders that no longer exist in source.) The shorthand switch to mirror directories is /MIR, so the command to mirror directories is:

C:\> ROBOCOPY C:\Temp1 C:\Temp3 /MIR

This results in the creation of C:\Temp3, and all of the files and folders under C:\Temp1 will be copied to the newly built tree under C:\Temp3. In addition, if C:\Temp3 already existed, any files in its tree that are not in the C:\Temp1 tree will be deleted from the C:\Temp3 tree.
