Robocopy command syntax and examples





Robocopy command is used on Windows to copy files and directories from one location to another. This CMD command also prints a detailed report of the copy operation. Below you can find examples for using Robocopy in various usecases.

Copy a directory

Example: Copy all the files in the directory D:\dir1\data to E:\backup\data. Don’t include sub directories or the files stored in those.
Robocopy  D:\dir1\data E:\backup\data
The above command copies system files and hidden files too. Copy and Xcopy commands skip these files by default.
At the end of the command execution, it would print the summary like below.
          Total    Copied   Skipped  Mismatch    FAILED    Extras
Dirs : 22 22 0 0 0 0
Files : 113 113 0 0 0 0
Bytes : 42.96 m 42.96 m 0 0 0 0
Times : 0:00:01 0:00:00 0:00:00 0:00:00

Copy directory structure

Run the below Robocopy command to copy directory structure i.e deep copy of folder hierarchy and the data in all the subfolders.

Robocopy /S D:\dir1\data E:\backup\data
This command does not copy empty directories. To copy them, you need to add /E switch.
Robocopy /S /E  D:\dir1\data E:\backup\data

Delete files and directories from the source after copying

You can add /MOV switch to delete files and /MOVE switch to delete both files and directories.

For deleting files:
Robocopy /MOV /S /E  D:\dir1\data E:\backup\data
For deleting files and directories:
Robocopy /MOVE /S /E  D:\dir1\data E:\backup\data

Modify file attributes for the copied files

Using robocopy command we can also change attributes(system, hidden, readonly) of the copied files. This affects the attributes of the files in the new location, it does not impact the files in the source directory.

For example to copy all files from one directory to another directory and also set hidden attribute for all the files you can trigger ‘Robocopy’ with the below syntax.
Robocopy /S /E  /A+:H D:\dir1\data E:\backup\data

Mirror copy a directory

Below Robocopy command creates a replica of the source folder in the specified destination folder
Robocopy /MIR sourceFolder  destinationFolder
This command also deletes any extra files that are present in the destination and are not present in source.

Replicate access permission on destination folder

The option ‘/sec’ copies all the file access permissions to the destination folder also.
 robocopy /sec sourceFolder destinationFolder
Note that Robocopy copies the security ACLs also to the destination only if the file has been modified. If the file has not been modified, the ACLs won’t be applied on the destination. You can check this Microsoft’s post robocopy file permissions for deeper understanding.
