APPARENT_SIZE

Tally usage based on apparent file sizes. Normally, the block-size is used, if available, as this is a more accurate representation of disk space used. Compare with du --apparent-size. Since GLib 2.78. and similarly to du since GNU Coreutils 9.2, this will ignore the sizes of file types other than regular files and links, as the sizes of other file types are not specified in a standard way.
