        - `falloc`: If you are using newer file systems such as ext4 (with extents support), btrfs, xfs or NTFS(MinGW

          aria2 entirely until allocation finishes. falloc may not be available if your system doesn't have

        WARNING:
            Using trunc seemingly allocates disk space very quickly, but what it actually does is that it sets file
