Copying Files
In computing, file copying is the act of creating a new Computer file, file such that it has the same content as an existing file. The operation is sometimes called ''cloning''. Generally, an operating system command-line shell (computing), shell provides for file copying via commands cp (Unix), cp, COPY (command), copy and similar variants. mv (Unix), mv also copies files but only when the source and destination are on different file systems. Windows also provides includes the more advanced tools: Robocopy and xcopy. Many operating systems also provide for copying files via a graphical user interface, such as a file manager. It may provide for copy-and-paste and drag-and-drop user experience. Notable third-party utilities: * FastCopy * Rclone * RichCopy * rsync * TeraCopy * Ultracopier Shadow copy Shadowing describes the process of maintaining a copy of a set of files, a.k.a. to Disk mirroring, mirror files in a separate physical location.

FastCopy
FastCopy is software for file copying on Windows. Originally open-source, under the GPLv3 license, later releases were freeware with a note that "Due to various circumstances, distribution of the source code is temporarily suspended". In version 5.0.0, licensing was changed for a newly added Pro version with additional features, and separated the use case in non-domestic environments, while previous versions allow using FastCopy in workplace. There are 32- and 64-bit versions, which run under Windows 7 and later, and Windows Server 2012 and later. The total size of the executable and DLL files comprising 64-bit version 4.1.7 is 1.3MB. It can run as a free-standing portable application or be integrated into the Windows shell, and claims to achieve reading and writing performance close to the device limit. In a test conducted in 2008 by lifehacker, Fastcopy was several times faster than its rival Teracopy, a program with similar functionality. However, both programs have be ...

Novell NetWare
NetWare is a discontinued computer network operating system developed by Novell, Inc. It initially used cooperative multitasking to run various services on a personal computer, using the Internetwork Packet Exchange, IPX network protocol. The final update release was version 6.5SP8 in May 2009, and it has since been replaced by Open Enterprise Server. The original NetWare product in 1983 supported clients running both CP/M and MS-DOS, ran over a proprietary Star network, star network topology and was based on a Novell-built file server using the Motorola 68000 processor. The company soon moved away from building its own hardware, and NetWare became hardware-independent, running on any suitable Intel-based IBM PC compatible system, and able to utilize a wide range of network cards. From the beginning NetWare implemented a number of features inspired by mainframe computer, mainframe and minicomputer systems that were not available in its competitors' products. In 1991, Novell in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
File Server
In computing, a file server (or fileserver) is a computer attached to a network that provides a location for shared disk access, i.e. storage of computer files (such as text, image, sound, video) that can be accessed by workstations within a computer network. The term server highlights the role of the machine in the traditional client–server scheme, where the clients are the workstations using the storage. A file server does not normally perform computational tasks or run programs on behalf of its client workstations (in other words, it is different from e.g. an application server, which is another type of server). File servers are commonly found in schools and offices, where users use a local area network to connect their client computers. Types of file servers A file server may be dedicated or non-dedicated. A dedicated server is designed specifically for use as a file server, with workstations attached for reading and writing files and databases. File servers may also b ...

Computer Storage
Computer data storage or digital data storage is a technology consisting of computer components and Data storage, recording media that are used to retain digital data. It is a core function and fundamental component of computers. The central processing unit (CPU) of a computer is what manipulates data by performing computations. In practice, almost all computers use a storage hierarchy, which puts fast but expensive and small storage options close to the CPU and slower but less expensive and larger options further away. Generally, the fast technologies are referred to as "memory", while slower persistent technologies are referred to as "storage". Even the first computer designs, Charles Babbage's Analytical Engine and Percy Ludgate's Analytical Machine, clearly distinguished between processing and memory (Babbage stored numbers as rotations of gears, while Ludgate stored numbers as displacements of rods in shuttles). This distinction was extended in the Von Neumann archite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows API
The Windows API, informally WinAPI, is the foundational application programming interface (API) that allows a computer program to access the features of the Microsoft Windows operating system in which the program is running. Programs can access API functionality via shared-library technologies or via system-file access. Each major version of the Windows API has a distinct name that identifies a compatibility aspect of that version. For example, Win32 is the major version of Windows API that runs on 32-bit systems. The name, Windows API, collectively refers to all versions of this capability of Windows. Microsoft provides developer support via a software development kit, Microsoft Windows SDK, which includes documentation and tools for building software based on the Windows API. Services This section lists notable services provided by the Windows API. Base Services Base services include features such as the file system, devices, processes, threads, and error handl ...

System Call
In computing, a system call (syscall) is the programmatic way in which a computer program requests a service from the operating system on which it is executed. This may include hardware-related services (for example, accessing a hard disk drive or accessing the device's camera), creation and execution of new processes, and communication with integral kernel services such as process scheduling. System calls provide an essential interface between a process and the operating system. In most systems, system calls can only be made from userspace processes, while in some systems, OS/360 and successors for example, privileged system code also issues system calls. For embedded systems, system calls typically do not change the privilege mode of the CPU. Privileges The architecture of most modern processors, with the exception of some embedded systems, involves a security model. For example, the '' rings'' model specifies multiple privilege levels under which software may be e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth
Earth is the third planet from the Sun and the only astronomical object known to Planetary habitability, harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering Water distribution on Earth, 70.8% of Earth's crust. The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is at least somewhat humid and covered by vegetation, while large Ice sheet, sheets of ice at Polar regions of Earth, Earth's polar polar desert, deserts retain more water than Earth's groundwater, lakes, rivers, and Water vapor#In Earth's atmosphere, atmospheric water combined. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's outer core, Earth has a liquid outer core that generates a ...

BIOS
In computing, BIOS (, ; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup). The firmware comes pre-installed on the computer's motherboard. The name originates from the Basic Input/Output System used in the CP/M operating system in 1975. The BIOS firmware was originally proprietary to the IBM PC; it was reverse engineered by some companies (such as Phoenix Technologies) looking to create compatible systems. The interface of that original system serves as a ''de facto'' standard. The BIOS in older PCs initializes and tests the system hardware components ( power-on self-test or POST for short), and loads a boot loader from a mass storage device which then initializes a kernel. In the era of DOS, the BIOS provided BIOS interrupt calls for the keyboard, display, st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disk Mirroring
In Data storage device, data storage, disk mirroring is the Replication (computing), replication of logical disk volumes onto separate physical hard disks in Real-time computing, real time to ensure continuous availability. It is most commonly used in RAID 1. A mirrored volume is a complete logical representation of separate volume copies. In a IT disaster recovery, disaster recovery context, mirroring data over long distance is referred to as storage replication. Depending on the technologies used, replication can be performed synchronously, Asynchronous communication, asynchronously, semi-synchronously, or point-in-time. Replication is enabled via microcode on the disk array controller or via Server (computing), server software. It is typically a proprietary solution, not compatible between various data storage device vendors. Mirroring is typically only synchronous. Synchronous writing typically achieves a recovery point objective (RPO) of zero lost data. Asynchronous replica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultracopier
Ultracopier is a file copying application for Windows, macOS, and Linux. It is based on and supercedes SuperCopier. SuperCopier and Ultracopier differ mainly in terms of appearance. SuperCopier essentially serves as a skin for Ultracopier, with slightly higher CPU usage. SuperCopier typically refers to SuperCopier 3 and earlier versions, while Ultracopier refers to SuperCopier 4 and later versions, now known as Ultracopier 1.4. Features include: *Pause/resume transfers *Dynamic speed limitation *On-error resume *Error/collision management *Data security *Intelligent reorganization of transfer to optimize performance * Plugins Normal vs. Ultimate version: *The source code is identical, and it falls under the same license. *The ultimate version includes alternate plugins. *Both versions are without DRM (as this is explicitly banned by the GPLv3 license) and can be redistributed freely. See also *FastCopy FastCopy is software for file copying on Windows. Originally open- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TeraCopy
TeraCopy is a file transfer utility focused on data integrity, transfer reliability and the ability to pause and resume transfers. It dynamically adjusts buffers to reduce seek times and provides asynchronous copying to reduce overall transfer time between two storage media. In case of a transfer error, the utility re-tries multiple times. Eventually, it skips the file and continues processing other files. TeraCopy shows failed file transfers and allows the user to retry failed operations. Since feedback about a failed transfer is limited to simply "Skipped", a user may struggle to fix the problem. With more detailed information (i.e. file name too long) the user might be able to better recover. The utility is designed to run as an application or integrated in Windows Explorer to replace its copy and move functions. The author asserts that it has full Unicode support. The utility is licensed as freemium. A basic edition is offered as freeware that is restricted to a non-com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
