What is the block size of the iphone filesystem?

Question

Is it worth it for me to compress a 1000 byte file to a 300 byte file? or will the filesystem space consumption be the same?

I\'m looking at storing 10k less than 4k

Answer 1

The iPhone uses an HFSX filesystem, with an 8k block size on the user partition:

int main(int argc, char *argv[]) {
  struct statfs *mntbufp = NULL;
  getmntinfo(&mntbufp, 0);

  unsigned i, count = 0;

  count = getmntinfo(&mntbufp, 0);
  for (i=0; i

returns

Volume / blocksize: 8192
Volume /dev blocksize: 512
Volume /private/var blocksize: 8192
Volume /Developer blocksize: 4096
