cp behaviour

[OUTWATER ~ KEITH J /5G3110]

Hello - 
I hope this is the right place to ask this question; if not, please direct me 
to 
the appropriate place.

I wish to use the fileutils in a classified environment to transfer data 
between 
computers and removable media.

In order to do this is is important that cp (and any related utilities) copy 
only the specified files without padding partial blocks with other data from 
the 
source filesystem (padding with a constant such as zero would be fine).


As an example, if a number of classified files (filesc) and an unclassified 
file 
(fileu) reside on the same disk, a cp of fileu to a floppy disk should never 
include any parts of filesc.

Are cp and friends safe in this regard?

Thanks!
