How do I open a DAT file? And how to modify it?

It's not associated with any program, so in Windows Media Player, you'll have to open it manually. In Windows Media Player, press Alt to press the pop-up menu list:

3. Select "File" from the pop-up menu, and then select "Open."."Command. Or press Ctrl+O directly to pop up the "Open" dialog box, and locate it to the directory where the sound ** is located:

4. The computer cannot display DAT files by default, you need to click on the right "** file (all types)" and select "All files (*.) in the pop-up drop-down listThen the audio ** file can be displayed:

Method 2: Text and program files.

1. If it is a program file of other software programs, most of these DAT files are data files used for installation or operation, and usually cannot be opened directly. You can try winhex to open it and see:

2. The other is a plain text file, which is actually similar to a txt file, which can be opened with Notepad, WordPad, UE, Winhex and other tools. This type of file is generally a configuration or backup file:

3. There are also special types of dat files, which can be opened but can only be garbled.

It will freeze when opened:

5. At this time, you can try to open it with special tools such as winhex, if you can't open it, don't open this kind of file.

I don't know what your DAT file is used for? The file extension of VCD is also dat, some data files are also dat, some of them are in text format, some are not, what file do you want to open? It's useless not to know the file format.

To open a file, you must first know its internal format, not its extension, which is just a hint of the internal format.

First of all: there is a difference between a text file and a binary file, for a text file, each byte (or every few bytes) has the same meaning, you just need to read it out one byte at a time; For binary files, there may be 4 bytes that hold an integer, and the next 4 bytes that hold a float and so ......onSo in order to open a binary, you need to understand its file format.

To know the file format, you can open a binary file with a hexadecimal and guess its format.

Or a professional texter opens the call format to try, because the programmer of each data is encrypted in the data, so some of the opening will be garbled.

So you have to be clear about what software your dat file was called before!!

dat for the most partThe dat file is the data used by the program, it is only defined by the developer himself in order to clarify the meaning of the file, and it can also be named with another extension! You can create a new file with any tool and name it.

dat。So,....There are also different tools for opening dat files, for example, some are actually text files, but the extension is rewritten.

dat, which can be opened with the text tool; The most common are VCD video files. Generally, these files are not directly used by the user.

For example, the DAT file in the VCD disc can be opened with a general **** device, while the DAT file of QQ stores user information, which cannot be opened in a conventional way, and only the QQ program can access it. There are a number of other programs that have their own definition of a DAT file that has to be opened through their own special program.

So in summary, there is no strict definition of a DAT file.

The DAT is not a standard document. Many software use this extension, but the file meaning is different.

For example, the VCD file is. dat

And many data analysis software also uses this extension to save data.

So it depends on the specific software situation.

This is a custom file format, you can't open it, you may be able to open it with his own plug-in, or not, the shutdown is a working style depending on how it is designed. It's not encryption, it's the kind of technology that you usually use to watch movie plug-ins.
