What you've described is the standard defined behavior of
findfirst()/findnext() according to the libc docs:

Any file that doesn't have any flag bits that aren't specified is
selected for the search.  Thus, if you specified `FA_DIREC' and
`FA_LABEL', you would get all subdirectories, the volume label, and 
any file that is neither read-only or modified.

Apparently, there's no way to make findfirst() _not_ list all ordinary
files.

However, you said yourself that the value of f.ff_attrib is 16 for
directories and 32 for files; it's simple enough to just ignore any
entries with values other than 16.
