How DAT files are opened

DAT is not a standard file. Many software uses this extension, but the file has different meanings. and many data analysis software also uses this extension to save data. So this depends on the specific software situation to decide. DAT files, which are meant to be data according to the extension, that is, data files, such files do not have an absolute definition, such as the VCD on the DAT file can be used in the general video player Open, and QQ dat files stored in the user information is not used in the normal way to open, Only QQ program can be accessed. There are other programs that have their own definition of DAT files to open their associated DAT files through their special programs.

DAT files can be VCD files, then use the player to open the line. But most of the time it is a data file, so don't open it, lest you break the data.

General VCD, then the size of this dat is relatively large, the largest can be more than 500 m (of course, there are many small VCD, depending on the length of VCD film). But the data format is generally relatively small, in hundreds of K or about a few m common. And VCD are movies, mostly in a Mpegav folder or a separate folder, data files are generally in the software or game folder.

Some data files for some software are also. dat extensions, which cannot be opened directly or converted to text files.

VCD file extensions are also dat, some data files are also dat, some of which are text format, some are not, DAT files how to open? It is useless to know the file format.

The first thing to open a file is to know its internal format, not to see his extension, which is just a hint of an internal format.

First: There is a difference between a text file and a binary file, and for a text file, the meaning of each byte (or every few bytes) is the same, all you have to do is read it one byte at a time; for binary files, there may be 4 bytes saved for an integer, then 4 bytes saved a floating-point type, and so on ... So to open a binary file, you need to know its file format.
