File size limit?

(1/1)

bmwcyclist:
Does anyone know the file size limit on HFS/MacWorks II+?

I have a ~600k file that copies fine on Baslisk II but not from an 800k image to the Lisa profile (FloppyEMU to ESProfile)

The maximum file size on an HFS volume is 2 GB.

On an MFS volume the limit is 20 MB - 400k disks are usually formatted as MFS, as are all disks initialized by Systems earlier than 2.1

By holding down the option key when clicking Initialize for a floppy disk, one can toggle the default of MFS for 400k and HFS for 800k.
Note that MW+ versions up through 1.1h aren't aware of this possibility and can mishandle the rare combinations of HFS 400k and MFS 800k disks. MW+II examines the disk to determine which format it has.

When the file does not copy, is there an error message?
