copy files using robocopy

Question

Hi All

My VM is hosted in Azure. I want to copy a folder (which contains subfolders and files, and some of the subfolder and file names exceed the 255-character limit) from one local drive to another. My local drive is the E drive, and the destination drive is the F drive, which is also a local drive. The purpose of copying the folder to the F drive is to detach this drive and attach it to another VM. I want to use Robocopy because some of the file and folder names exceed 255 characters, even if one file is missed then the application may not work. However, when I execute the command below in PowerShell, I receive an error:

PS C:\windows\system32> ROBOCOPY E:\myfolder F:\myfolder /copy /e

Answer 1

Hi @Roger Roger ,

did you try this already?

robocopy E:\myfolder F:\myfolder /mir /e

The reason why your command fails might be because the parameter /copy expects another value: Copy options

Answer 2

Hello,

Thank you for posting in Q&A forum.

This problem is caused by the wrong parameter options of the robocopy command. I suggest you run the following command:

robocopy E:\myfolder F:\myfolder /copyall

I recommend you to refer to the following links:

I hope the information above is helpful.

Best regards
