The correct answer is A. XCOPY/D : date.
The XCOPY command is used to copy files from one location to another. The /D switch specifies that only files that have been modified on or after the date you specify should be copied. For example, to copy all files from the C:\Users\username\Desktop folder to the C:\Users\username\Documents folder that have been modified on or after January 1, 2023, you would use the following command:
xcopy /D "C:\Users\username\Desktop\*" "C:\Users\username\Documents"
The COPY command is also used to copy files, but it does not have a switch that allows you to specify a date. The COPY/M switch specifies that only files that have been modified should be copied, but this does not include files that have been modified on or after a specific date.
The XCOPY/V switch specifies that the destination files should be verified after they are copied. This is useful for ensuring that the files were copied correctly.
The answer E is incorrect because it is not a valid MS-DOS command.
