Because this is a base of indexed files in GNOME. Also surprised that file "/home/mikhail/.local/share/Steam/steamapps/common/Deus Ex Mankind Divided/share/data/runtime/game.layer.0.all.archive" are divided on 20511 parts, although on the partition is enough free continuous space for store this file as one indivisible part. The purpose of my research was to show that despite the fact that with average 1.75 extents per file, is possible find files on the disk that, for some unknown reason, are divided on 20K parts. -- Best Regards, Mike Gavrilov.
