It has to be continuous, and for a partition used as a subdirectory has to also 1) start at a 40-block boundary (i.e. from the start of a track) and 2) the size must be N*40 blocks (N >= 1, but N>1 makes sense). > 2) where in the directory entry is detail for "start" and "end" track for > the partition stored I can't check this right now, but I think it simply was the starting T&S bytes just as for plain files. The size is in the size bytes. > 3) are files stored only in the partition space allocated between "start" > and "end", or can the whole disk be used. Only within the selected partition/subdirectory. The bitmap for a subdirectory has the outside area and the allocated blocks of the subdirectory's directory track marked as allocated. The directory track of a subdirectory is the first track in the partition, not the middle one as for the root directory. > The disks I've looked at seem to show blocks free for the whole disk > (though all blocks for the partition are relected in size of the CBM file) Clarification: The partition blocks are allocated from the parent directory when a partition is made. The fullness of the subdirectory does not change the 'blocks free' of the parent directory. -Pasi -- /'And give him 10000 crowns to do whatever he wants.' This was a fortune.
