Now, a lot of coffee cups latter, I am thinking maybe it is harder to
"securely" delete a single file than a whole disk or partition...
since
with just 1 file, you must overwrite the place where the file is
located, and if we want to erase the whole disk, it should be matter
of
filling it up to full capacity with some debris data... there is no

to "aim" to a specific spot...
Exactly right. Shredding a whole disk is like using a hammer.
Shredding a single file involves a scalpel. It's a lot harder - not
impossible, but harder - to use a scalpel.
