VHD (Virtual Hard Disk) and its successor VHDX are file formats representing a virtual hard disk drive (HDD). They may contain what is found on a physical HDD, such as disk partitions and a file system , which in turn can contain files and folders .
The virtual disk is implemented as either split over a collection of flat files, typically each one is 2GB in size, collectively called a split flat file, or as a single, large monolithic flat file. The pre-allocated storage scheme is also referred to as a thick provisioning [6] scheme.
In fact, files in a virtual folder do not even need to be stored as files on the hard drive. They may be on a network share or in a custom application datastore such as e-mail inbox or even a database. Documents cannot be "stored" in a virtual folder, since physically a virtual folder is just a file storing a search query.
A logical disk, logical volume or virtual disk (VD [1] or vdisk [2] for short) is a virtual device that provides an area of usable storage capacity on one or more physical disk drive(s) in a computer system. The disk is described as logical or virtual because it does not actually exist as a single physical entity in its own right. The goal of ...
Virtual disk and virtual drive are software components that emulate an actual disk storage device.. Virtual disks and virtual drives are common components of virtual machines in hardware virtualization, but they are also widely used for various purposes unrelated to virtualization, such as for the creation of logical disks,software development, testing environments, and data management.
Users of PCTask could create a file of large size on the Amiga filesystem, and this file would be virtually accessed from the emulator as if it were a real PC Hard Disk. The file could be formatted with the FAT16 filesystem to store normal MS-DOS or Windows files.
VMDK (short for Virtual Machine Disk) is a file format that describes containers for virtual hard disk drives to be used in virtual machines like VMware Workstation or VirtualBox. Initially developed by VMware for its proprietary [ 1 ] virtual appliance products, VMDK became an open format [ 2 ] with revision 5.0 in 2011, and is one of the disk ...
Disk partitioning or disk slicing [1] is the creation of one or more regions on secondary storage, so that each region can be managed separately. [2] These regions are called partitions. It is typically the first step of preparing a newly installed disk after a partitioning scheme is chosen for the new disk before any file system is created.
