PerfectDisk
PerfectDisk is a defragmentation software product for Windows developed by Raxco. The application keeps track of file usage to lessen defragmentation time and offers two modes of basic defragging: "quick" and "SmartPlacement". History During the 1980s, a software package titled "Disk-Optimizer" was marketed as part of the collective name "RAXCO Rabbit Software." PerfectDisk was released in 1990 for the VMS operating system. A version for Windows NT followed later in 1997. PerfectDisk contains scheduler supporting also client PCs in the network. The last version of PerfecDisk is 14.00 build 900. As Raxco filled for bankrupcy in April, 2024, PerfectDisk users can still use the installed software, but no activations will be done after May, 2024, and no support will be provided past this date. Competition The standard Windows "Disk Defragmenter" is based on a subset of a competing, now-discontinued product named Diskeeper. For those seeking additional features, PerfectDisk and th ...

Raxco
Raxco Software Inc. was a Gaithersburg, Maryland software company. Founded in 1978, the company's products have been sold internationally. The company spun off one division as ''Axent Technologies''; the latter was "acquired by venture capital firms in 1988." Meanwhile ''Raxco'' continued with its own product offerings. PerfectDisk became its flagship software package. Raxco transitioned from its 1980s"RABBIT Software from RAXCO ... speed up response times, .. improve your through-put without having to purchase more (hardware)" and 1990s VAX (OpenVMS, VMS) and OpenVMS software product line, and did a management buyout to become a private, independent company. Interim ownerships From the later 1990s thru the early 2000s, corporate ownership of the two organizations transitioned: * Raxco spun off one division (Axent) * Axent Technologies Inc, * Axent was acquired by Symantec * Symantec dropped some of its acquisitions in 2001.

Windows XP
Windows XP is a major release of Microsoft's Windows NT operating system. It was release to manufacturing, released to manufacturing on August 24, 2001, and later to retail on October 25, 2001. It is a direct upgrade to its predecessors, Windows 2000 for high-end and business users and Windows Me for home users, available for any devices running Windows NT 4.0, Windows 98, Windows 2000 and Windows Me that meet the new Windows XP system requirements. Development of Windows XP began in the late 1990s under the codename "Windows Neptune, Neptune", built on the Architecture of Windows NT#Kernel, Windows NT kernel explicitly intended for mainstream consumer use. An updated version of Windows 2000 was also initially planned for the business market. However, in January 2000, both projects were scrapped in favor of a single OS codenamed "Whistler", which would serve as a single platform for both consumer and business markets. As a result, Windows XP is the first consumer edition of W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
File System Fragmentation
In computing, file system fragmentation, sometimes called file system aging, is the tendency of a file system to lay out the contents of files non-continuously to allow in-place modification of their contents. It is a special case of data fragmentation. File system fragmentation negatively impacts seek time in spinning storage media, which is known to hinder throughput. Fragmentation can be remedied by re-organizing files and free space back into contiguous areas, a process called defragmentation. Solid-state drives do not physically seek, so their non-sequential data access is hundreds of times faster than moving drives', making fragmentation a non-issue. It is recommended to not defragment solid-state storage, because this can prematurely wear drives via unnecessary write–erase operations. Causes When a file system is first initialized on a partition, it contains only a few small internal structures and is otherwise one contiguous block of empty space. This means that th ...

Computer System Optimization Software
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proprietary Software
Proprietary software is computer software, software that is deemed within the free and open-source software to be non-free because its creator, publisher, or other rightsholder or rightsholder partner exercises a legal monopoly afforded by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting his or her freedoms. It is often contrasted with Open-source software, open-source or free software. For this reason, it is also known as non-free software or closed-source software. Types Origin Until the late 1960s computers—large and expensive mainframe computers, machines in specially air-conditioned computer rooms—were usually leased to customers rather than Sales, sold. Service and all software available were usually supplied by manufacturers without ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defragmentation Software
In the maintenance of file systems, defragmentation is a process that reduces the degree of fragmentation. It does this by physically organizing the contents of the mass storage device used to store files into the smallest number of contiguous regions (fragments, ''extents''). It also attempts to create larger regions of free space using compaction to impede the return of fragmentation. Some defragmentation utilities try to keep smaller files within a single directory together, as they are often accessed in sequence. Defragmentation is advantageous and relevant to file systems on electromechanical disk drives (hard disk drives, floppy disk drives and optical disk media). The movement of the hard drive's read/write heads over different areas of the disk when accessing fragmented files is slower, compared to accessing the entire contents of a non-fragmented file sequentially without moving the read/write heads to seek other fragments.

Diskeeper
Diskeeper is a discontinued defragmentation app, designed for Microsoft Windows. It was developed by Executive Software International, Inc., which later changed its name to Diskeeper Corporation, and is now called Condusiv Technologies. The final version of Diskeeper was released in March 2020. All of Diskeeper's features and functionality are now included in Condusiv's data performance software DymaxIO. History Originally, Diskeeper was developed for the VAX series of minicomputers and later for Microsoft Windows. The defragmentation program which is included with Windows 2000, Windows XP and Windows Server 2003 is based on a basic version of Diskeeper. Diskeeper 9.0 (for Windows 2000 and XP) Server Edition introduced Terabyte Volume Engine (TVE), which provides optimal defragmentation performance on volumes of 1 TB and larger. Diskeeper 2008 Professional introduced a Volume Shadow Copy Service (VSS) compatibility mode, which defragments on a unit of 16 KB, so that VSS file his ...
