copy all files and folders from one drive to another drive using DOS (command prompt)

xcopy "C:\SomeFolderName" "D:\SomeFolderName" /h /i /c /k /e /r /y

Use the above command. It will definitely work.

In this command data will be copied from c:\ to D:, even folders and system files as well. Here’s what the flags do:

• /h copies hidden and system files also
• /i if destination does not exist and copying more than one file, assume that destination must be a directory
• /c continue copying even if error occurs
• /k copies attributes
• /e copies directories and subdirectories, including empty ones
• /r overwrites read-only files
• /y suppress prompting to confirm whether you want to overwrite a file
• /z Copies over a network in restartable mode.
