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
