The Catalog File, which stores all the file and directory records in a
single data structure, results in performance problems when the system
allows multitasking <>,
as only one program can write to this structure at a time, meaning that
many programs may be waiting in queue due to one program "hogging" the

The HFS Plus Catalog File is very similar to the HFS Catalog File
<>, the main
differences being records are larger to allow more fields and to allow for
those fields to be larger (for example to allow the longer 255-character
unicode file names in HFS Plus). A record in the HFS Catalog File is 512
bytes in size, a record in the HFS Plus Catalog File is 4 KB in Mac OS and
8 KB in OS X. Fields in HFS are of fixed size, in HFS Plus the size can
vary depending on the actual size of the data they store.
