Hmm.. OK, not being a Mandriva user myself (and therefore do not know what Desktop Environment you are using), I can only make some general comments, and leave it to some other users to add more comments or suggestions:
1) If in the KDE environment, the Konqueror file manager allows you to drag+drop items, such as
file icons. When one releases the 'drop' button (i.e. let go of the mouse) a dialog asks if you want to "Copy, Move, or Link" the item. I don't know that there's a specific special term for this sort of drag+drop functionality - but perhaps some other members can suggest other file managers besides Konqueror (if you don't use that) that can do the same thing. Or, just research them yourself in the meantime; Google for "Linux File Managers" and check out their features. Examples are ROX, Fileman, Konqueror, Nautilus... See here for more:

The above would also apply to moving files/folders from a hard disk onto let's say a CD or USB stick - it will ask "Copy, Move, or Link" - so it leaves the original where it is if you want.
2) As for "Making a CD with Windows" - the same would apply on Linux, whether you're burning some files to a CD in a storage sense, or if you're making an ISO, such as a bootable disc; and it's also the same whether you burn your files using the command line, or you use a burning app like K3b or Brasero: the original files should remain where they were, UNLESS you specifically tell the burning tool to MOVE the files or delete the originals. I believe that would not be the default behavior though - the files normally are left untouched, and you end up with a CD too. I burn stuff via command line, but my roommate uses Brasero and her original files are left where they were after burning.
Sorry, I'm not aware of the name of the "file helper" you refer to; but I hope the rest of this helps a bit. It's been quite some time since I've used a file manager, so I'm not up to date with the latest/common features of the best known ones out there.
