The maximum numbe=
r of directory entries is 64,000 if all of the
entries have names th=
at are 15 octets or less in length. A name that
is 15 octets long req=
uires the use of only one block in the directory.
Additional sequent=
ial blocks are required to store entries with names
that are longer t=
han 15 octets. Each additional block provides an
additional length o=
f 32 octets for the name of the entry.=20
Note that if file names use a=
n encoding like UTF-8, a single
character may be encoded into multipl=
e octets. In real world use, the
maximum number of objects in an AFS=
directory is usually between
16,000 and 25,000, depending on the av=
erage name length.
