History
XTree 1.0 was officially introduced on April 1, 1985 at the West Coast Computer Faire and sold for $39.95. Work had begun on XTree in December 1984. The primary developer was Jeffery C. Johnson, who was working for a company named Executive Systems Inc. (ESI). Additional contributions were made by ESI owners Dale Sinor, Tom Smith, and Henry Hernández, as well as Ken Broomfield who did quality assurance. The XTree name was the concept of Johnson's wife, Arletta, who had made the suggestion: "'XTree'. You know, like 'X-Tree, X-Tree read all about it!'". Johnson claims to be the originator of the visual directory tree concept that was used first in an Epson backup product created by ESI. The tree command found in later MS-DOS releases displayed directories in a markedly similar fashion. By 1991, XTree had sold over 3 million copies and was released in over a half-dozen languages.
Even in its earliest version XTree contained features like listing all files of a branch including subdirectories, listing of all files on a disk, or viewing a file's contents in text or hexadecimal format (regardless of its file extension), that the Windows file manager is not capable of even in its latest Windows 7 version.
XTree was supplemented by the enhanced XTreePro in 1988, which added features for working with multiple disk drives, speed improvements, and brought the keyboard commands more in line with other common DOS programs. A version of XTreePro with Novell Netware connectivity debuted in late 1988. XTreeProGold/XTreeGold succeeded Xtree Pro in 1989, adding pull-down menus to enhance the interface, additional file viewers, and the choice of a Norton Commander-style split pane between locations on different disks. The first GUI-enabled XTree product was XTreeMac, also launched in 1989, which brought the XTree interface metaphors to the Macintosh System as a Finder replacement. While the Macintosh System software already had competent file management, XTreeMac made it easier to move and copy files and added undelete and enhanced file finding tools.
Also in 1989, the company ran a four month 'Software Amnesty for Everyone' allowing users of pirated copies of XTree to register them for a small fee. 5,000 licenses sold for $20 each.
XTree suffered a terminal decline after the widespread adoption of Microsoft Windows. The built in Windows file manager had a vaguely similar appearance to XTree, and while it lacked the speed, keyboard shortcuts and power, it did benefit greatly from being included with Windows.
In 1992 XTree for Windows was released. The product dropped many of the features liked in the DOS versions, with undeletion and file editing particularly noticeable by their absence. The program also took considerably longer to load than both DOS Xtree and other Windows file managers, and operations like viewing files were slower. Despite this, features like native support for file compression and a wide range of file viewers made it the most feature complete Windows file manager of that year. It was not a success for the company. In 1993, the XTree Company was sold to Central Point Software, which was in turn acquired by Symantec in 1994, and in 1995 production of XTree products was halted.

Famous quotes containing the word history:
“To a surprising extent the war-lords in shining armour, the apostles of the martial virtues, tend not to die fighting when the time comes. History is full of ignominious getaways by the great and famous.”
—George Orwell (1903–1950)
“There are two great unknown forces to-day, electricity and woman, but men can reckon much better on electricity than they can on woman.”
—Josephine K. Henry, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 15, by Susan B. Anthony and Ida Husted Harper (1902)
“A poet’s object is not to tell what actually happened but what could or would happen either probably or inevitably.... For this reason poetry is something more scientific and serious than history, because poetry tends to give general truths while history gives particular facts.”
—Aristotle (384–323 B.C.)
