Robocopy examples

robocopy c:\blah c:\blah2 *.txt

In this first example, any .txt file would be copied from the blah folder into the blah2 folder.

Whenever you want to copy one or more files and not a complete folder the file must be specified after the destination folder.


robocopy c:\blah c:\blah2

In the above example, the robocopy command would copy all files (not folders) in the blah folder to the blah2 directory.


robocopy c:\blah c:\blah2 /e

In the above example, all files and folders (including empty ones) will be copied from the blah folder to the blah2 folder.


robocopy c:\blah c:\blah2 /MIR

This example will MIRror what is in c:\blah into c:\blah2 and purge any files in the blah2 folder that do not exist in the blah folder.

Use the /mir switch CAREFULLY since it will be deleting files in blah2 that do not exist in the blah folder.


robocopy \\computer\blah C:\blah2

This example would copy any of the files in the blah folder on the network computer named 'computer' to the current computer's blah2 folder.
