What program to open dat. What is a DAT file and how to open it. How to open dat file

DAT file is a universal container that can contain any information. This could be plain text, a picture, a video, streaming audio, game saves, passwords, and the list goes on for a very long time. Typically, the user may encounter this file in an email Email. The reason for the arrival of such a file may be that some kind of failure occurred during the sending or receiving process.

A wide variety of applications use them as references to specific operations in their respective program. This application could ultimately be any other file such as a document, image, etc. There are undoubtedly dozens or hundreds of others.

Typically, you can't change a file extension to one that your computer recognizes and expect the newly renamed file to be used. This data may be plain text, or it may be the binary encoding of an image, video, or other file.

Once you know the encoding format, you can change the file extension and allow your computer's default handler to open the file. Launch Notepad, select "File" and then "Open." If the file is plain text, you will do the following: it will be human accessible. Otherwise, look for clues in the binary data about the encoding or file type of the file or the tool that created it.

To successfully open a DAT file in Windows, you must first find out which program created it. If you know the type of this file, then it will be much easier for you to select the right program and get data from the file. But if everything doesn’t work out so well, and you really don’t know or doubt the content, then the tips listed below will be useful to you.

Once you know the data type, rename the file with the correct extension so your system knows how to open it. If you can't determine the type, try renaming the file to a generic image or video extension anyway to see if it opens.

Under Folder Options, select Show hidden files and folders. People often wonder how to open and read mysterious data files. Choosing a program to open such files sometimes becomes a big question. Well, you're not alone! But you don't know which program will be suitable to open such a file. But don't all files just contain data? All computer files do contain some or other data. Here you may ask a question: what happens if we change the file extension?

Finding out detailed information about the DAT file

There are special programs that determine the file type. They also help you choose a program with which to view the data.

Method 1: File Type Verifier

File Type Verificator is a free program that will greatly simplify the task of identifying a DAT file. It is easy to use, so there should not be any serious difficulties.

Elementary ways to open a document

So it will ask you to select a program to open the file. So, you will see the file name, but not the file extension. After completing these steps, all file names will be shown along with their extensions. Ideally, the program that generates the file should give the correct extension to the file.

How to open dat

What are the common examples. The reason for this practice is that these video files should not be opened by the user. If the computer opens the file and displays legible content, then no problem! This is where you have to start with some guesswork.

• Check the file size.
• If the file size is large, it is most likely a video file.
• Emails may contain malicious attachments.

You may see a lot of gibberish in Notepad.

As you can see in the screenshot, the DAT file contained a JPG image, which can be opened in any program that supports image viewing. You can try to open the photo using File Type Verificator.

The image will open in the program associated with the file type. In our case, the picture opened in a standard photo viewer.

It can show you any file in hexadecimal form and you can try to figure out the parent program exactly like you tried in Notepad. You will likely find the parent program easy to find. He is a web explorer and enjoys finding useful information on the Internet. He loves to put things together to create a larger solution.

Lalit is passionate about technology, languages ​​and literature. File extensions usually tell your computer something about a particular file and how to open it. The file may contain machine language. Scroll down in the file to see if any readable content appears after the machine language.

Method 2: Win Hex

Win Hex is a powerful utility that has many features. It is often used by professionals or simply experienced users. For beginners it is difficult. The capabilities of this program are very large; they are not limited to simply determining the DAT of a file. For example, it can edit RAM, giving access to the virtual and physical memory of processors. Also, there is a function to restore erased data. But unlike the previous program, WinHex is shareware. Additional features are purchased, but our task is only to study the DAT file, so we do not need them.

Servers sometimes change file extensions because the file is received via email. Translating technical jargon into everyday English is one of Annie Martin's specialties. She is an educator and writer who has taught and produced documentation for over 13 years at the University of Missouri. He holds a master's degree in educational technology and a bachelor's degree in journalism and political science from the University of Missouri.

Method 1

This front end approach is not a fancy solution, but it works great. Besides how popular it may not be a wise decision anyway. There are several ways to view files. This will not change the file type. Only dedicated conversion software can change a file from one file type to another.

This software is available in English. If you are uncomfortable using this language, then you can change it to Russian.

Let's move on to the file definition itself.

This file was created in the photo editor Photoshop, therefore, we can conclude that this is an ordinary picture. You can open it in any program that supports image inspection.

Create a new email message as normal. Select "Plain Text" from the drop-down menu. Scroll to the bottom of the dialog box. The spreadsheet should contain one row of variable names at the top of the table in the first row. Variable names must include regular letters, numbers, and underscores and not include special characters. Missing values ​​for string or numeric variables have empty cells or an appropriate predefined missing value code.

The path must use a backslash and must include the full filename after the last backslash.

• The data must start in the first column, second row of the table.
• Anything that is not part of the data itself must be removed.

It is only possible to read one sheet at a time, even if your workbook has multiple sheets.

Method 3: Total Commander

Total Commander is a multifunctional file manager that also allows you to view DAT files. The program has many features. For example, it has a built-in special archiver and supports various useful plugins. Shareware or requires registration, but this does not prevent you from freely using it for 30 days.

Importing data from a text file

If you want to import more than one sheet, you will need to read each sheet separately. In the File type list, the default option is “Text”. The Text Import Wizard window will open. The window provides a preview of the data in your text file. The first step is to indicate whether the data follows a predefined format, which will be saved in the format saved in the previous text file, imported using the Text Import Wizard. In most cases there will be no predefined format.

Other methods

You can do it easier by double-clicking on the file. The system itself will offer a program to open. But this does not always happen, so you have to resort to alternative methods.

Follow these steps in the Import Wizard to import text data. Delimited: Variable values ​​are delimited in the file by a special character, such as a comma or tab. Fixed width: Variables are aligned in fixed-width columns. In the What delimiters appear between variables area, select the check box that reflects the delimiter used in your data. A separator is what is used to separate values ​​from each other in data. If you don't know what delimiter is used in a text file, consult the documentation associated with your data or ask someone who knows how the data file was created.

Common types of DAT files

The most common types are several formats:

There are a large number of different file dates. As you can see, there is nothing complicated about opening such files. The main thing is to know in which program it was created and then you will not have any problems with it.

Uncheck the box next to Space and the change will be reflected in the preview. Note, however, that there was at least one instance where the Major's observation was incorrectly split into two columns. Notice how the meaning is double quotes before the first word and after the last word. These quotations are used as text classifiers; that is, they indicate where the observation begins and ends. To fix this, we need to change the text classifier option to double quote.

Programs that can be used to open the .DAT file

This step allows you to specify the format of each variable in the data file. You can select any of the variable names to change the data format. As a final step, you can save the file format you just defined for the current data file in case you need to use it for future file inputs. Saving the syntax will allow you to format future data files in the same way without having to manually select each option in the Import Wizard.

A newer format is called "Region", in which regions of the level are contained in a .MCR file. Patch 1.2.1 introduced the "Anvil" format and files with the .MCA extension.

DAT files in Minecraft have varied throughout the game's releases. Therefore, a .DAT file from one version of the game may not be compatible with another version.

Today's topic of our article is related to another file extension. In case you have problems working with this format and you don’t know what a dat file is, how to open such a file - don’t worry, we will provide detailed information, with which you can see what kind of data is stored in the desired file.

Why is DAT format needed?

In short, a DAT file can contain almost any data format - text, video, audio stream, images, and much more. The type of program that created the dat file will determine what information is stored inside.

In order to clarify which program to open the dat file, you can use specialized programs - this can be File Type Verificator or Win Hex. Using one of the specified programs, we look at the name, and knowing it, we select the necessary utility.

These actions should be carried out only when you do not know exactly which program should be used to open your dat file and where it came from.

Often, a DAT extension file is used in one of three cases; we will consider each of them in detail below.

Data file - most likely use case for DAT

The DAT1 extension file (short for Data File) is a format for storing data from a wide variety of applications. Most often in this case, the data inside the file is presented in text form or in binary form. This is where the question arises “how to open a dat file” - in this case, such a file can only be opened in the program with which it was created. Data presented in text format can be viewed using one of the many graphic editors:

• Standard Windows Notepad;
• Wordpad (also standard);
• Notepad++;
• Far (or Total Commander)
• STDU Viewer (or Acrobat Reader)
• WinDjView
• (or free Libre Office Writer)

Examples of programs that use files of this extension (and, accordingly, which can open these files in this case) include a number of programs - MS Visual Studio, Winamp, Corel Word Perfect, Ontrack EasyRecovery.

If your file was created by one of the above programs, the question of how and which program to open the date file is no longer a mystery for you.

DAT extension for storing mail attachments - winmail.dat

The contents of winmail.dat in this case represent formatting information text messages sent using email software from MS - Outlook from office suite, or mail server Exchange. In this case, the winmail.dat file is added to the very end of the messages. This is done to ensure that the message is correctly received and viewed even if the client email program does not support RTF format messages.

List of programs for opening a DAT file for the case in question:

• Microsoft Mail;
• MS Outlook;
• WinMail Opener (or WinMail Decoder);
• WMDecode;

DAT format for storing VCD/CD video data

A file with this extension may well contain video content - data recorded on a VCD (short for Video CD). As a rule, in this case MPEG-1 or MPEG-2 compression is used. However, VCD player programs can automatically play these files. Let's take a few of them as an example:

• VCDGear;
• CyberLink PowerDirector;
• River Past Video Cleaner;

Separately, I would like to say that there are wand dat files - they are also used to store various credentials - . These files can be viewed using the Unwand program.

Finally, I would like to note that if you have no idea where the file of this extension came from, you should not wonder how to open the dat file - with a high degree of probability it will turn out that it does not contain any useful information for you.

A file with the .dat extension is found in almost all programs installed on a computer terminal. Naturally, many users wonder how to open DAT file, especially since there are a lot of prerequisites for such interest. The fact is that this extension can correspond to a huge number of programs, although in most cases it is essentially information files, the format abbreviation of which is derived from the English Data. Let's try to figure out what's what.

Options for using DAT files

As for what this extension is associated with, there can be quite a lot of options. Therefore, it is absolutely impossible to say that any program for DAT files is universal. The most interesting thing is that even applications that can open files of this type are completely different in their focus.

For example, not to mention storing data, a DAT file can be an archived email attachment, a registry file, a computer game compatibility file, a cache file in Internet Explorer, video file, DOS or Windows data file, etc. As you can see, there are quite a lot of options. Let's look at the most basic ones.

Text editors

The most simple method The solution to the problem of how to open a DAT file is to use a regular text editor like Notepad or a more advanced version like Notepad++, which is capable of displaying the syntax of a programming language.

True, there is one nuance here. At best, the user will see a mass of strange characters, less often - binary code. So this method is only suitable for extreme cases, and then only after using utilities like Disassembler, which allow you to restore source after compilation.

Registry Files

One of the most common is the DAT file in the form ntuser.dat, which is registry data that stores user information (directory key HKEY_CURRENT_USER).

In principle, there is no need for an inexperienced ordinary user to open such a file, since incorrect handling of the system registry and the entries stored in it can lead not only to undesirable, but even catastrophic consequences.

Games

Sometimes DAT files are a means of saving settings or completed levels in a particular game. In addition, the use of files of this type also has the meaning that games from different manufacturers can be compatible with each other due to their settings. This is especially true for files like level.dat, in particular in the game Minecraft.

Uninstallers

Some files with the .dat extension can be used by application installers and uninstallers. In particular, application installation and uninstall files created using Inno Setup may contain in the root directory with installed program special file unins000.exe, to which the DAT file is attached, which is responsible for the correct removal of the application.

Cache

In the question of how to open a DAT file, another variation is the solution associated with the usual means of accessing the World Wide Web using Internet browser Explorer. The DAT file is a cache. In other words, such a file stores data about changes to pages visited, for example, if the page itself remains unchanged when refreshed or returned using the “Back” button. True, this technology is no longer relevant and is used only in older versions of IE.

For many browsers, such files can be used as a means of storing personal data such as logins and passwords for accessing certain Internet resources.

Email

Among the most common formats of this type are email attachments, messages of which are created or received using the included Windows utilities called Microsoft Outlook and Microsoft Exchange.

In this case, the file is called winmail.dat and is responsible for the correct sending and receiving of messages in terms of formatting. This is especially true for receiving messages by email clients that do not support the .rtf format.

Video

The most popular previously was the DAT file format, which was a video. On this moment this technology is outdated. However, some old digitized video recordings can still be found today.

Unfortunately, not a single program of this type, which allows you to understand how to open a DAT file, establishes its own association with this format. So you have to open files of this type in manual mode, indicating the path through various menus such as “Open”, “Play”, etc.

The most simple example CyberLink PowerDVD application can serve. Essentially, the DAT file in this case is the same container in which the source material is packaged using the MPEG-1 or MPEG-2 codec. In principle, discs on which such video is recorded are usually called VCD (or Video CD). As is already clear, this format has not been used for a very long time.

Conclusion

As you can see, DAT files are in most cases very specific and relate more to the software environment. So, in general, it’s not worth opening them, unless it’s an outdated video format. All the same, for the average user they will be, to put it mildly, useless.
