Hello Listers, Recently there was a bit of discussion on HFS-Wrappers on the hfs-user mailing list and how it allows a computer with HFS (but no HFS Plus support) to start up or display a ReadMe to the user to improve the user-experience. The tech. notes (TN 1150: HFS Plus Volume Format) says that the HFS wrapper volume contains five files in the root folder - a ReadMe, System and Finder, Desktop DB and Desktop DF.
I'm a third-party developer creating an HFS-Plus volume (non-bootable) interested in extending the functionality of my HFS-Plus volume to include a Wrapper as well. I want to know whether:
1) these 5 files are actually necessary or it would suffice if only the ReadMe is present ? 2) would this mean that the Desktop DB and DF files would be present twice (on an Apple-initialized volume) ? - once in the HFS-Wrapper and once in the HFS-Plus catalog ? 3) is there any documentation from Apple which describes how this ReadMe file is stored up in the Wrapper's catalog (I gathered it's not hidden) in order to function as expected ?... reverse-engineering can be painful sometimes.. 4) are the contents of the ReadMe file fixed or could I write anything I want into it ?
Would be glad of any tips/suggestions ! -Nandini
