Not at all.  These utilities all rely on the DOS functions, which are
supplied in the IFS.

For instance:
DIR - Finds first file, finds next file, etc.
MV/CP etc - Find file, open file, load file, open file, write file, close
files (in case of mv, deleting)

Of course, the IFS functions will differ, but that's the whole point of
an IFS.
