What are files and how they are
Any operating system is a set of related files, each of which performs a unique function. Moreover, each operating system understands only a limited number of file formats, which determines its file system. This list can be supplemented by installing the appropriate programs or various emulators. Such actions do not expand the capabilities of the operating system itself, but only allow the user to process information presented in other forms.
What are files (computer has nothing to do with it)?
If we digress from computer subjects, then this question can be answered in the following way: a file is a special plastic container for paper documents of various formats (meaning paper format). Such terminology is associated with the meaning of the word "file", which came from the English language, as a container of information. Therefore, having heard the buyer's request in some store to sell him a couple of files, you should not think that in this department they trade in illegal content.
What are files (and here already)?
A file is a special area on a disk that contains any information and has a unique name. If to be more conservative and say the same thing in an academic language, the definition is structured as follows: a file is a named area of a disk that stores a certain amount of information in it. In simple terms, one can say that everything that a person sees on the monitor screen is files. They can be of different sizes, extensions (a few characters after the dot, defining its type — a program with which it can be opened) and encoding. In addition, the files can be executable (they serve to run programs), text, graphic, extensions (functional libraries) and specialized (for each type of program).
How to explain to the child what files are
If such a need arises, you should avoid complex concepts and long formulations. It is better to call everything by its proper names (with the words that “spin” in the language). For example, an icon, a picture, and even a generalizing "everything that is on a computer." To help you, you can call specific icons that serve to depict each type of file on your computer — icons.With them the process of learning computer skills and familiarity of the child with the operating system is greatly simplified.
How to decrypt files
In most cases, special compiler programs or binary editors are used to decrypt files. In order to understand this need, it is worth remembering what files are. At its core - information that is translated from human language to "computer", understandable only for programmers and the operating system. In some cases, the file can be decrypted using the simplest text editor, such as Notepad, for example. This suggests that the data is written in standard form, and the file itself is a “script” (script).
Which file system is better for a flash drive?
This question can be answered only if it is sufficiently clear to know for what purpose the flash drive will be used. If it is designed to work with digital cameras, cell phones or other mobile equipment, then the USB flash drive must be formatted (marked) in FAT format. If it will be used only on a computer, then it is advisable to mark it in NTFS format.This will not only save disk space, but also protect information from many computer viruses.
