1. Software license types


The application is free, but we have to see advertisement block.


Generally it is free, but during the installation or running it offers any additional services (sometimes very annoying) like different toolbars or shareware utilities installing, browser homepage changing or some other tools, that allows developers to earn some money from their application.


Regular paid software. No paying - no running.


Demonstration version. You can run and try it, but it would save nothing without paying.


The application is fully free and has no limitations, but you can cheer an author with some money if you want.


Completely free application without any limitations and conditions. As they say, "all for people".


GNU General Public License is a license which allows us not only to use a software, but also change it with our needs. And you will not be punished for it :)


To start an application you have to register at the author's site or to send him a letter with the description of your plans for using his product.


The free version has a functional artificial limitations. For example, you may have a limited number of launches or working with not all file formats or some other limitation. It allows you to look itself in action, but will ask to pay for the full version.


The program works for the certain time (until the term of the trial license expires).

  • DOC is a file extension for word processing documents; most commonly for Microsoft Word. Historically, the extension was used for documentation in plain-text format, particularly of programs or computer hardware, on a wide range of operating systems. During the 1980s, WordPerfect used DOC as the extension of their proprietary format. Later, in the 1990s, Microsoft chose to use the DOC extension for their proprietary Microsoft Word word processing formats. The original uses for the extension have largely disappeared from the PC world.

  • HTML (Hypertext Markup Language) is the predominant markup language for web pages. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. It allows images and objects to be embedded and can be used to create interactive forms. It is written in the form of HTML elements consisting of "tags" surrounded by angle brackets within the web page content. It can embed scripts in languages such as JavaScript which affect the behavior of HTML webpages.

  • PHP (Hypertext Preprocessor) is a widely used, general-purpose scripting language that was originally designed for web development to produce dynamic web pages. For this purpose, PHP code is embedded into the HTML source document and interpreted by a web server with a PHP processor module, which generates the web page document. As a general-purpose programming language, PHP code is processed by an interpreter application in command-line mode performing desired operating system operations and producing program output on its standard output channel. It may also function as a graphical application. PHP is available as a processor for most modern web servers and as standalone interpreter on most operating systems and computing platforms.

  • TXT is a filename extension for files consisting of text usually containing very little formatting (ex: no bolding or italics). The precise definition of the .txt format is not specified, but typically matches the format accepted by the system terminal or simple text editor. Files with the .txt extension can easily be read or opened by any program that reads text and, for that reason, are considered universal (or platform independent).
