Changing the iso size from file size to space used

Sparse size

Sparse size should be shown because

• all (non-modified) ISOs are the same size (GC 1 459 978 240 B, Wii 4 699 979 776 B) but the content size vary
• the ISO padding should be sparse rather than removed (called trim in Wii Scrubber) because the latter is a more advanced modification leading to boot failure on the native hardware for some ISOs in some USB loaders
• there's a command line tool to efficiently
  • sparse multiple files wit scrub *
  • backup rsync -aSv --progress /cygdrive/l/rom/ /cygdrive/e/backup/rom, move mv, copy cp with retained sparse information

@delroth

I'm not sure if st_blocks unit size == 512 is a valid assumption to make, especially with 4K sectors disks.

st_blocks is 512 B for AF too

Is there any reference to the fact that st_blocks always counts 512 bytes blocks?

The quote "the number of blocks allocated to the file, 512-byte units"

[03:16] @Sonicadvance1 JPeterson, Pull request #18, no

What's the reason that you oppose the change?
