File Extension QPW
File extension QPW is most commonly associated with a Quattro Pro for Windows project file. Quattro Pro is a spreadsheet application produced by Corel, and is usually bundled with the WordPerfect Office suite.
Quattro Pro for Windows (QPW) project files contain information in spreadsheet form, and were one of the earliest formats to support tabbed workbooks. This idea was first used by rival Boeing Calc, though Quattro Pro was the first application that was genuinely quick enough to make it usable. Quattro Pro and was originally developed by Borland as a rival to Lotus 1-2-3, though was later sold to Novell before finally being taken on by Corel.
QPW files are workbook or project files, which can contain one or more spreadsheets. Data is stored in rows and columns, with each individual data item contained within a single cell. Each cell has a unique reference which comprises of the column and the row that it is contained in. Numerous data types are supported to aid the presentation of information within a spreadsheet as well as calculations to be performed using appropriate formats such as currency. Spreadsheets within QPW files can also contain formatting, such as stylised text or coloured cells to aid readability, as well as formulas which can perform complex calculations quickly, or be used to create data models. Charts and graphs can also be embedded within spreadsheets to display information, and can update dynamically to reflect changes to data within the spreadsheet.
Support for QPW files is limited, and they can only be successfully opened using Quattro Pro, which is part of the Corel WordPerfect Office suite. Corel do provide a fully working trial version of their office suite, which can be used to open a QPW file and export it in another format for use with another spreadsheet application.
