copying files to transfer from one PC to another
copying files for safe keeping or for record purpose
copying files from the hard disk to floppy disks
All of the above E. None of the above

The correct answer is: D. All of the above

The COPY command is a versatile command that can be used to copy files from one location to another, or to make a copy of a file for safekeeping. It can also be used to copy files from one type of storage device to another, such as from a hard drive to a floppy disk.

Here are some examples of how the COPY command can be used:

  • To copy a file from one directory to another, you would use the following command:

COPY source_file destination_file

For example, to copy the file “myfile.txt” from the current directory to the directory “c:\temp”, you would use the following command:

COPY myfile.txt c:\temp

  • To copy a file to a floppy disk, you would use the following command:

COPY source_file /A:

For example, to copy the file “myfile.txt” to the floppy disk in drive A, you would use the following command:

COPY myfile.txt /A:

  • To make a copy of a file for safekeeping, you would use the following command:

COPY source_file destination_file /Y

The /Y option tells the COPY command to overwrite the destination file if it already exists.

For example, to make a copy of the file “myfile.txt” and save it as “myfile.bak”, you would use the following command:

COPY myfile.txt myfile.bak /Y
