How to use cat append one file without deleting the original

I'm using the following command to merge some files in multiple folders to one. 

$dir=`ls`; for d in $dir; do files=`ls $d`; for f in $files; do cat $d/$f>>../results/$f; done; done

But after doing that, the original one is missing, how can I do that without deleting the old one.

Thanks.

Still unsure if I get your point correctly, but anyway, here`s the code:

$dir=`ls`
$res=$(ls ../results)
for d in $dir; do
    files=`ls $d`
    for f in $files; do
        grep -q "$f" "$res" && f="${f}1"
        cat $d/$f>>../results/$f
    done
done
