Copying files and
subdirectories
Copy compares the filename of the input file with the filename
of the target. If they are the same, that one input file is skipped,
and MS· DOS prints the error message "Content of destination lost
before copy." Further joining proceeds normally. For example, thl"
following command appends all *. txt files (except all. txt) to
alltxt:
copy all.txt + *.txt
This command will not produce an error message.
If you want to copy files and subdirectories, you should use the
xcopy command. Refer to the xcopy command in this chapter for
more information on how to do this.
