FileCore 256GB limitation

Would it be possible to allocate bit 12 in the FileCore disc flags to indicate if a FileSystem supports 64bit addressing?

This would allow software to be future proofed to support 64bit address via DiscOp64, once FileCore and associated FileSystems are updated to support it.

This will tell you whether the Block Drivers aka associated Filesystems support 64 bit addressing, but not whether FileCore will actually use it.

The underlying FileSystem indicates to FileCore that it supports 64bit addressing. If FileCore doesn’t support 64bit, it clears the bit allowing both the FileSystem and anyone interrogating MiscOp 6 to determine if 64 bit address will work on that FileSystem.

FileSystems that don’t support 64bit won’t attempt to set the flag, so it covers 64 bit on both FileCore and the FileSystem with one bit.
