HI, Everybody

Wishing u all a very Happy Holi.( An Indian festival played

with colours)

Well in the MDB structure for an HFS volume the

field

vol.drXTClpSiz /* clump size for extents overflow file */

is 4 bytes long.

Again in the Catalog Data Record structure the member

filClpSize; /* file clump size */

takes 2 bytes.

Therefore when i assign the value of the first variable to

the second I lose information.

But then one way is to make the MDB's variable contain

a value only for 2 bytes then assignment won't make

a data loss. But the value for the MDB's variable was

calculated as 1/128 th part of the Total volume size.

An emphirical formula used in the hfsutils package.

Any comments on this???

Please is there any simple formula to find out the

extent file size and the catalog file size for a volume

when we know before hand how many files have to be

in that volume.

For eg. if i know i have to write "X" files contained in

"Y" number of directories.

Then can i calculate what should be the volume's

clump size for the extents overflow file and the catalog

file.

Waiting for ur explanations.

Bye
