This 1src thread made me think about 8 GB VFS volumes and if they are possible with existing OS5 Garnet devices(that have the FAT32 driver installed).
To be honest, I now “know” that this is probably impossible for a simple reason: downwards compatibility and variable size for the VFS manager API. To explain the situation, the VFS manager API is the interface that programs use to talk to external memory cards. It uses UInt32 variables for most calls, so the maximum adressable/returnable size is 4 GB(2^32).
Dmitry Grinberg has reported that he already has a patch for 8GB SD cards..but as said, no 8GB volumes for unpatched handhelds!
