Presuming that the deletion rate is much less than the retention rate, a simple
4DOS batch program could be used to prune the unwanted files from H: (along
with directories which became empy), after which the "copy /u
/s" command could be used:

for /a:-d /r h:\ %f in (*.*) if not exist E%@instr[1,%@full[%f]] del/xy
%f
del/s/x/a:d e:\
copy /s /u e:\*.* h:\

N O T   T E S T E D !

The advantage, of course, is that presumably the time saved by not formatting
and not copying old files is less than the additional time needed to remove
"leftovers".

It might also be useful to have some form of validation, e.g., a comparion of
CRCs.
