The RedSea file system is a simple, 64-bit, file system which is similar to FAT32, but with absolute block addresses instead of clusters, fixed-sized 64-byte directory entries and no FAT table, just an allocation bitmap.  A cluster is just one 512 byte sector.  Files are stored in contiguous blocks and cannot grow in size.

The following bit field shows valid 8-Bit ASCII filename characters.

File with names ending in .Z are stored compressed.
See $LK,"implementation of LZW compression",A="::/Kernel/Compress.CPP"$.

To replace ISO9660, make hard-drive partition image of a measured size and copy onto a CD/DVD starting at about sector 20, with EL TORITO booting.  512-byte sectors will be placed on top of 2048-byte CD/DCD sectors, so there will be four blocks per CD/DVD sector.

RedSea file system has no bad block table and no redundant allocation table.
