Where are the text formats used? Text files are often used to store service information (for example, logs) because of their simplicity: since the operation of adding new data to the end of a text file does not require any significant computing resources, regardless of the already existing file size and the type of text data to be added, log files usually occur effectively and unnoticed for the user and for other applications.
The text format serves as the basis for many more specialized formats (for example, .ini, SGML, HTML, XML, TeX, programming languages source code. In some of these formats, certain symbols combinations can be used as markup tools. In this case, the file can store formatted text, in which characters can additionally be given a font, font, size, etc. (for example, Rich Text Format, HTML). PDF is also text format or text and graphic format. If it is a 100% text format, you will convert PDF to Word without any loss of quality.
The .txt extension is usually used for files with unformatted text in DOS and Windows. However, text files can be files with any other extension or without it. For example, program source code is usually stored in files with extensions that correspond to the programming language on which programs are written (.java, .bas, .pas, .c).
Formatted text (text with markup) is usually stored in files with the extension corresponding to the format or markup language - .rtf, .htm, .html.
The .pdf extension means that file will include all necessary fonts, media, raster and vector images. The text also will be protected via password and high security protection encryption way. If compare PDF to Doc, the first will be the winner.
Simple 8-bit text provides the software simplicity and independence from the problem of the order of bytes or the length of the computer word on different platforms. A disadvantage is a large number of different standards, which can lead to incompatibility.
The use of Unicode in text files, although basically solves the "encoding problem" and standardizes the use of symbols control. Also, Unicode texts have an even greater redundancy than 8-bit ones.
All text extension was created to transfer the text and the only PDF were invented to transfer with protections from any changes. It really works! To make some changes into PDF files you need to know the password and then convert PDF to Doc, text format.
