Folder
A named container for files that are stored on a volume.
A folder can contain other folders (sometimes called subfolders).
In the file system (p. 72), a folder is a table that contains a description of files (p. 72) and other
folders. Such a structure allows creation of a folder tree that begins with the root folder (p. 76).
Foreign disk
A dynamic disk which is a part of a foreign dynamic disk group (p. 73).
Foreign dynamic disk group
A group of dynamic disks that is not native for the currently running operating system.
To be able to use such disks, you need to import them to the existing disk group on the machine.
Formatting
The process of creating a file system on a volume.
After the volume is formatted, you can place files and folders on it.
Fragmentation
The scattering of parts of a file across different areas of the volume.
As a result of adding, deleting, and changing files, many files can occupy space on the volume in
multiple non-contiguous pieces. This requires more time to access such files.
The defragmentation (p. 70) process aims at improving access times by making fragmented files
contiguous.
Free space
Space on a volume that is not occupied by data such as files and folders.
Not to be confused with unallocated space (p. 78) on a disk.
G
GPT disk
A disk whose partitioning scheme (p. 76) is GUID partition table (GPT).
GPT disks are typically used by 64-bit operating systems, such as Windows XP Professional x64
Edition.
See also MBR disk (p. 75).
GUID partition table (GPT)
One of the two partitioning schemes of a disk. See in Partitioning scheme (p. 76).
