File formats (types)

click fraud protection

Everyone who at least once in the life of a personal computer, knows that all files have a specific format.Read it by clicking on the file name.It has the following form: the first part - is the name given by the user, which is closed by a point;second - you formats.Those with whom we are accustomed to deal with, often are the most common.For movies - is .avi, for music - .mp3 and .wav, and for photos - .jpg.However, there are plenty of other file extensions.On them, we discuss in this article.In addition, we look at the main program, by which these files can be opened properly.

Open file formats for viewing

very first comment that the user may have, is that he can not see the file format on your computer.That is, it will be available for editing (changing), and read only the base file name, not the data after removal point format.If you have such a situation, do not worry, nothing wrong with that.

Windows operating system has the ability to hide file formats.This is done for a more comfortable computer use for those people who do not change the format, and they need only a PC for data, maybe even for home use.Enable or disable hiding format is simple enough.You must be in the "Service" - a point which is at the top of any folder window, and then select the pop-up menu, "Folder Options."It is, accordingly, will open a dialog box where you can edit the features of the display of folders and files.There will need to click the "View" and place (or remove) a check in the "Hide extensions for known file types."If extensions are hidden, the format will not be displayed.

file format.The program is the main purpose

Besides the fact that you need to consider how to get the computer to show and hide the format, you must also give a short explanation of the so-called target program, which can be opened file.Yet it can be called the main purpose of the program.

Here's the thing: the same file formats can be opened in different applications.For example, .jpg opens as programs for viewing images and graphics editor to edit it.Yet they can be opened and imported into the software to create presentations, for example.However, after some of our application, we will open a picture in .jpg, depends on our goals - what we want to do with it.Therefore, in the following explanations will consider this as well.

text files with formatting

begin with a description of files containing formatted text.Of course, the most common of these is the file format Word (.doc, .docx).They can easily transfer text from the advanced settings (such as headers, page layout, and so on).These files are edited easily on all versions of Microsoft Office Word (.docx files, with the exception of the program in 2003 and earlier).Most people use this particular word processor, capable of transmitting text format.

In addition, you can call another format - .rtf, which also can be opened and Word, and other, more simple editor - WordPad.

And, of course, one can not forget that there is a file in format .pdf.He is able to transmit not only text information (stored, for example, through the Office Word), but also contain graphic elements.Paste can be through the image editors such as Adobe Photoshop.

files with text format without

If we talk about the form in which you can find text files, you can not, of course, do not name the most popular extension.Though it is not capable of transmitting text formatting: headings, images, tables, etc. - yet the characters themselves, and text characters best conveys file format .txt.

Create and read his best with the help of the basic editor, which is available on all PCs (and even not only on the operating system Windows).This is the "Notepad".

for whatever purposes you may create one or the other text, it's easy and convenient to do it with this program.It can be as sticky notes "at hand" on the desktop and system files, are intended to be placed on hosting or data collection using the scripts and programs.

Graphic Apps

certainly an important role in working with a computer for each of us plays a schedule.And no matter what you do: simply demonstrate your holiday pictures to friends, or create a design for the site - in each of these, as well as in many other cases, you will find graphic file formats.

Typically, this well-known and .jpg .jpeg (most common), .bmp (created using standard drawing with Paint), .png (icons, capable of maintaining a transparent background when moving pictures), .gif (animated images, comprisingseveral frames) and .psd (standard file Photoshop, preserving the working area of ​​the image).Of course, the graphic files are much bigger, but facing them is not all.Let's start with the main areas of analysis where we are working with graphics.

View graphics

course, all image file formats can be opened for viewing.Some (such as .gif, .jpg and .png) can be viewed using the basic software for viewing images installed on any Windows;others can be revealed only with the help of special programs for editing (for example, .psd file or CorelDraw).In this case, the image will not only watch, but also to change as you please.

advantage of the program to see that they can comfortably acquainted with the content (sometimes on a large scale).In addition, there are applications that can hold small manipulation of photos (like the creation of additional illumination, the elimination of the effect of "red eye" and others).Of course, they can be called and editors, but formally they relate to such a provision, which only makes it possible to inspect images.

Image Editing

On a more profound change photos and pictures, you can not do without editors.Of course, there are plenty of narrowly focused programs to easily and quickly perform a particular operation (eg, resize the photo or the imposition of filters).However, the most versatile and flexible in any case remains Photoshop.With this program do not need to think about how to open the file format of the graphic content - it supports the widest range of extensions.And it is noteworthy that the vast majority of them can resist the changes.Features that PS gives its users, is simply unrealistic to list.

music files from a photographer's move to the music and recordings - even demanded of one category of content among PC users.Of course, we should mention the file format .mp3.It's the most popular extension, which is able to guarantee high-quality sound of your music.It is compatible with almost any device that plays media files.

further be noted formats .wave (which at one time was actively used on mobile phones that do not support .mp3), .aac, .aiff, .flac, .ogg.Differences between this or that aspect lies in the fact that some of them use the audio compression and therefore lose sound quality.Others do not resort to such a distortion, but files are more cumbersome.

Open an audio file, you can use any player.The most popular of them support a huge number of formats.

Movies and video

Those who often looks serials or any movie, know perfectly well that such files are provided mainly in the form .avi.This is the best option from the category "format for saving files" in terms of visual and sound data, as it is capable of displaying a high quality on the maximum number of devices.However, apart from him, of course, you can watch video in lower quality, but older versions of mobile phones (.3gp), as well as the format .mp4 (for the older generation of players), .mpeg, and others.

Again, as in the case of audio recordings, you can open them with any video player on Windows or MacOS.

format webpages

you know that many of the web addresses end in .html.Strange, is not it?It would seem that as a page on the Internet may end as well as the file extension?

It's very simple!In fact, going to a particular resource, we refer to this file.And of course, if you see .html file format on your computer, you can be sure: in front of you web page.How do I open it?

It all depends on the purpose of launching such a file.For example, if you simply need to view the contents and the way code is displayed - you can safely use a browser (Google Chrome, Opera, Mozilla - your choice).

In the same case, if you want to change the page, you need to run it with a text editor from the most simple, "Notepad", and ending with a comprehensive solution for creating web pages - Adobe Dreamweaver.

System files and execution

So finishing consider these types of files, such as music, pictures, movies and Web pages, move on to another equally important category of data with which we all face very often - it systemicfiles.

As a rule, we know that they play an important role in our system.And we try not to touch them, so as not to run into problems at the operating system level.These files often come in the form .dll, and we used to ignore them.

Another category - execution files having extension .exe.We know that if you run the file, then open the program or application to which it relates.Often, downloading from the Internet is an unknown file type file.exe, we can also see a warning anti-virus application, signaling the threat of such files.

Indeed, .exe can run a wide range of scenarios on your computer, so they should be to be careful.

What happens if you change the format?

Another touch on a topic such as the selection of the program, with which you can open a file of a format.

fact that many of these extensions are so flexible that they can be opened through various applications.As an example, .jpg.In a typical photo viewer, you will see the picture itself, whereas in Photoshop you will open the whole working area, allows you to change the image that you want.

This is a good example of the complex actions that are available in each individual case depends on the software with which we work.If you open the index.html file in a browser, you'll see a page of the site, while the notebook is to be mass lines with the code.And so on.

The truth, of course, change the program to open different types of files can be within reasonable limits.Let's just say: open an audio file using Notepad, you can, but what you'll see, will not talk to you about anything: it is the mass of the encoded information is displayed as "characters."

hide file extensions

So, we had a brief tour of file formats, which often deal end users.Of course, many more.And it is clear that not every one you worked personally.Just maybe, you did not think about the purpose of several formats, and now they will become a little clearer.

Now, if you are uncomfortable constantly see the type of a file for some reason (for example, you do not accidentally change the format of the title), you can disable this feature.This can be done in the "property" of any folder, tick "Do not show file extensions."Most home computer users do experts give advice in this way, so as not to get confused as to which is the format of the file when it is renamed.
