What documents does a data room contain?

Computer users in any country perform very similar tasks on it. Most computers have similar programs: various editors (text, spreadsheet, graphics, audio, and video), browsers, players, archivers, antiviruses, image viewers, and so on.

With such a “total” use of similar software, their file formats inevitably become popular, the most common.

Text files

.txt is the first format for text files that do not use formatting (font size, bold, paragraph indent, etc.). Contains only text.

.doc is a format used for a long time in Microsoft’s Word text editor. Most common for text editors.

.docx is a format for the Word text editor from Microsoft, which appeared in the Microsoft office 07 (2007) package and is available in Office 10. Not all editors support this format since this is a licensed development from Microsoft.

.pdf is a text file format developed by Adobe. It is available in smaller sizes and renders images better than other formats. When it was designed, an editor to create such files had to be purchased from Adobe. At the same time, any user could download a viewer for this file. Many companies made text information in this format, so it became popular.


There are a large number of file formats for drawing. One of the first was .bmp, which contains a different color value for each pixel. Therefore, it is the most voluminous among other formats. On the other hand, it renders colors best. Over time, other formats for drawings appeared that contain compression algorithms: .gif, .jpg, .png, .tif.

Since not all devices and programs support all formats, it is sometimes necessary to convert a picture to the most common form, for example, .jpeg. To do this, you can use both format conversion programs, or you can enter a graphics program that supports the picture format and then immediately save it, but in a common form.


The most common formats are: .midi, .mp3, .wav. The .midi format differs in that it contains notes and is used mainly with a synthesizer. Therefore, its size is the smallest. However, you cannot record your voice in it. There are other formats, for example: .aa, .aac, .ac3, .amr, .cda, .imelody, .imy, .flac, .m4a, .ogg, .qcp, .wma, .xmf.


The most common format was .avi, but it can use different types of compression, so the movie may not play on the video player. For the video player to play more video files, you need to use a codec that installs subroutines that allow you to decrypt the video data stream, for example, k-lite. Here is a list of other formats: .3gp, .avi, .aaf, .flv, .mp4, .mpeg, .mov, .vob, .wmv, .mts and many others.


Archive files are used on a computer not to store large files since they are created using a compression procedure. The earliest is the .zip format, which can be unpacked using operating system tools. Other archive files require special programs to work with them.
