The limits of HFS are as follows:
2GB limit on data forks
16MB limit on resource forks
32767 files in a single folder
65536 files on the whole volume
The limit on the size of the volume changed over time, with early
versions being limited to 2GB for the volume, then 4GB, then 2TB.
The larger partition support was added in the System 7.5.x series
There is also a limit of 65536 allocation blocks, which means that
in a practical sense, you can't have more than a few thousand files.
HFS+ removes most of these limits by using 32 bit numbers for a lot
more types of data, and 64 bit numbers in a couple places.
