How to open unknown files?

The fact is that each file, be it a song, video or document, has its own extension. The extension is what is written after the name of the file itself, for example, you have a file called a picture.gif, that is, a file named image has the extension .gif.

What is an extension and what is it for?

The extension indicates the structure of the file, that is, it informs the computer what kind of file it is: photo documents or pictures have extensions. gif ; . jpeg ; .bmp; .img; .jpg, etc. Text documents - . txt ; . doc ; (scanned magazines, books - .djvu; . pdf), etc.

That is, the extension indicates to the OS which program can be used to open this or that file, and if the required program is not installed on the system, then naturally the file will not open.

How to open a file knowing its extension?

To enable the extension display, do the following:

Click “Apply” and “OK”. That's it, now all files on your PC will be displayed like this:

Many information materials on the Internet can only be downloaded in pdf format, but many users do not know what to do next with such documents or how to open such a file on a computer. That is why we decided to dwell on this issue in more detail.

What is pdf format?

PDF, or Portable Document Format, is a text and multimedia file format that is independent of a computer system. Since this method of presentation is very convenient, it is in this way that program installation guides, instructions, reference books and catalogs are usually made.

But it is impossible to open and view PDF on a computer without installing special applications. The Windows 8 operating system has a built-in tool for viewing such documents, but its operation often does not satisfy users, and additional programs have to be installed.

How to open a PDF file on a computer?

There are many applications designed to work with this format. Let's look at the most popular:

. This is the most common program for working with the PDF format. By installing this software, any documents will be opened easily and quickly, like regular text files. Additional features include the function of adding comments and annotations. The only disadvantage of the Adobe product is that it periodically experiences glitches that slow down the computer.
. The program takes up little space in the device's memory, but it works quite quickly. Compared to Adobe, Foxit Reader has fewer functions, but if you plan to use the software only at home, this program will be quite enough for you.
. A simple utility designed not only to open PDF files, but also other similar formats. In addition, this software is ideal for computers with low power.

This is a collection of utilities for editing, reading, and flexible printing of PDF files.

With this application, the user can not only open and view any PDF file, but also make some adjustments to it.

Using Adobe Reader as an example, let's look at how easy it is to work with PDF files.

The first step is to download the Adobe Reader program itself (Figure 2).

Note: When you download, you'll be prompted to install the optional McAfee Security Scan product. If you don't need it, just uncheck the box next to the program's name.

After this, you need to wait for the download and double-click on the downloaded file. The installation comes down to the standard procedure: launch, select the installation location, click “Next” and after a few minutes of waiting, when a message appears indicating that the installation is complete, click “Finish” (Figure 3).
