Declined Fragmented jpstree.jpx

Every time I recreate jpstree.jpx it gets fragmented all over the disk in 30 to 40 fragments.

I wondered if there is something you could do that would not take too much work to create it contiguously.

  • write the whole thing in one physical i/o without an aux buffer.
  • write it over top of the existing defragged jpstree.jpx file. It might grow a tad, but that would be just 2 fragments, corrected at the next defrag run.
  • do a dummy write to allocate the max size, then fill in.
