Because APM allows 32 bits worth of logical blocks, the historical size of an APM formatted disk using small blocks [3] is limited to 2 TiB. [ 4 ] The Apple Partition Map maps out all space used (including the map) and unused (free space) on disk, unlike the minimal x86 master boot record that only accounts for used non-map partitions.
Disk Inventory X is a disk space analyzer utility for Mac OS X 10.3 and later. Inspired by WinDirStat, it shows the sizes of files and folders in a graphical treemap.. Version 1.3 of Disk Inventory X added support for macOS 10.15 Catalina, while the earlier version 1.2 added support for macOS 10.14 Mojave and its dark mode feature.
While storage devices usually have their size expressed in powers of 10 (for instance a 1 TB Solid State Drive will contain at least 1,000,000,000,000 (10 12, 1000 4) bytes), filesystem limits are invariably powers of 2, so usually expressed with IEC prefixes.
Available for Linux, Mac, Windows, Solaris, AIX and IRIX. Asymmetric. Dell Fluid File System (formerly ExaFS) proprietary software sold by Dell. Shared-disk system sold as an appliance providing distributed file systems to clients. Running on Intel based hardware serving NFS v2/v3, SMB/CIFS and AFP to Windows, macOS, Linux and other UNIX clients.
If the actual size of the disk exceeds the maximum partition size representable using the legacy 32-bit LBA entries in the MBR partition table, the recorded size of this partition is clipped at the maximum, thereby ignoring the rest of the disk. This amounts to a maximum reported size of 2 TiB, assuming a disk with 512 bytes per sector (see 512e).
This specifies the size of the chunks of data as delivered by dd, and is unrelated to sectors or filesystem blocks. In Linux, disk sector size can be determined with sudo fdisk -l | grep "Sector size" and block size can be determined with sudo blockdev --getbsz /dev/sda. [14]
Filelight is a graphical disk usage analyzer part of the KDE Gear.. Instead of showing a tree view of the files within a partition or directory, or even a columns-represent-directories view like xdiskusage, it shows a series of concentric pie charts representing the various directories within the requested partition or directory and the amount of space they use.

In 1998, Apple introduced HFS Plus to address inefficient allocation of disk space in HFS and to add other improvements. HFS Plus is still supported by current versions of Mac OS, but starting with Mac OS X , an HFS volume cannot be used for booting , and beginning with Mac OS X 10.6 (Snow Leopard), HFS volumes are read-only and cannot be ...
