★What is the file suffix
To say that the Windows work interface under the file name is simply arbitrary, for example: an editorial department of the 2000 work plan. The file name can be expressed directly in Chinese, and the length of up to 256 characters, so people look really clear. However, in the Windows environment, the installation of the software is a large number of similar CALENDAR.EXE, GAMES.GRP and so on the name of the file, which is why? It turns out that these filenames are based on the DOS environment's filename naming rules.
★DOS environment of the file suffix
In DOS, the file name using the 8 + 3 structure, that is: the longest 8-bit filename, separated by the decimal point and then followed by the longest 3-bit suffix, such as: READ.ME, SETUP.EXE, in general, the filename does not allow the use of Chinese characters, can only be made up of letters, numbers, and some symbols. Such as READ.ME with the Chinese understanding is "read me", that is, prompting the user to use the software before looking at the contents of this file to get more information about the prompt. What's more, DOS specifies that suffixes are used to distinguish between different kinds of files.
The first and easiest thing to encounter under DOS is executable files, with two types of suffixes: *.exe, *.com (where * means any filename), which are programs compiled in assembly language or other high-level languages and run directly under DOS. Sometimes due to the software functions, memory is small, not all at once into the memory may also have the same file name ovl file, such as ws.exe, ws.ovl. There is another kind of file can be run directly, *.bat, that is, batch files: there are a number of commands or executable file names, mainly used to improve work efficiency; the most useful is Autoexec.bat, the file will be automatically executed when booting up the computer. The most useful is Autoexec.bat, which will be executed automatically when you boot up your computer (Automatically execute is Automatically execute in English). Another kind of file that can be loaded but cannot be run directly is the system extension management file *.sys (sys means system): it mainly provides drivers for some non-standard devices such as mouse, memory expansion, etc., such as mouse.sys and himem.sys. In order to unify the management of a special config.sys text file to automatically call in these files when booting up, once and for all. The driver can also be used as a driver for any device, such as mouse.sys, himem.sys, etc. For unified management, a config.sys text file has been specified to automatically load these necessary device drivers at boot time.
The files generated by word processing under DOS could have been created without a suffix, but they are commonly referred to as *.txt (txt is text). It is supported by all platforms and all applications. In order to manage the convenience, people can also use their own name as a suffix to indicate that they built the text file, such as I entered a lot of articles that is *.mcj, in order to facilitate the user in the case of accidental deletion of the original file can be restored as soon as possible to the original file, many word processing systems provide a kind of automatic backup function, such as the second time I edited the JIHUA.MCJ (JIHUA: the plan for the MCJ), the system will first make a copy of the original file as JIHUA.BAK. The use of word-processing software with special formatting features, such as Mr. Bojun Qiu's early years of the introduction of the WPS, will provide for a .wps suffix to identify the text file generated with WPS. When using word processing software to edit high-level language programs, the suffix is usually the first three letters of the corresponding language (e.g., *.BAS that is, BASIC language source programs, *.PAS for PASCAL language programs, *.FOR for Fortran language programs, *.C that is, the C language, *.ASM that is, assembly language programs).
Along with the executable file is often accompanied by the following types of files: *.HLP that is, the help file (help), *.CFG that is, the configuration file (config), *.DAT that is, the data file (data), *.LOG that is, the log file (log), *.TMP for the temporary file (temporal).
★Windows file suffixes
The vast majority of DOS file name suffixes continue to be valid under Windows, but Windows itself has led to a number of new suffixes, such as: *.drv for the device driver (Driver), *.fon and *.fot are font files, *.grp for the Group file (Group), *.ini for the initialization of the information file (Initiation), *.pif for the DOS environment executable file in Windows execution of the file format required, *.crd that the card file (Card), *.rec that is, the recorder macro file (Record), *.wri that the text file (Write) It is word processing write.exe generated files, *.doc and *.rtf is also a text file (Document), they are Word generated files, *.cal for the calendar file, *.clp is the clipboard file format, *.htm and *.html that is, the home page file, *.par for the exchange of files, *.pwl for the password file (Password) and so on. Password) and so on.
★Extensions for image files
Entering the world of multimedia, you will see all kinds of wonderful images, and you will find many kinds of extensions. Indeed, the fact that various companies have created their own standards for developing graphics-related software has led to the fact that there are so many formats available today for graphics, and here are a few of the common ones:
First, there is a bitmap file format, which is a set of dots (pixels) that make up an image, and which are either generated by an image program or created when an image is scanned. The main ones are Windows Bitmap (.BMP): developed by Microsoft, it is supported by the Windows and Windows NT platforms and many applications. It supports 32-bit colors and is used as a resource file format for creating icons for Windows interfaces. cursor (.CUR, .DLL, .EXE): resource file format used for creating cursors for Windows interfaces. os/2 Bitmap (.BMP): Bitmap file format developed by Microsoft Corporation and IBM. It is supported by various operating systems and applications. Compression is supported, and the maximum image pixels are 64000 x 64000. paintbrush (.PCX): introduced by Zsoft, it compresses image data as well, and can be generated by PCX. Paintbrush for Windows. Supports 24-bit color, maximum image pixels are 64000 x 64000. supports compression. Graphics Interchage Format:
Graphics Interchage format (.GIF): Created by Compu Serve, it supports drawings at any size, saves storage space through compression, and also allows multiple drawings to exist in a single file. It supports 256 colors, and the maximum image pixels are 64000 x 64000.

Supported by the Macintosh platform, only supports monochrome original images, the maximum image pixels is 576×720. supports compression, mainly used for saving black and white graphics and clip art pieces in Macintosh graphic applications.
★Animation file extensions
Animation file formats are used to save graphical information contained in animation frames. The main ones are: Autodesk FLIC (.FLC): i.e. .FLI, the animation file format for Autodesk Animator and AnimatorPro. Supports 256 colors, maximum image pixels are 64000 x 64000, and compression. Widely used for animated sequences in animated graphics, computer-aided design, and computer game applications. Not well suited for animating real-world images.
MacPICTS (.PCS, .PIC): animation file format developed by Macromedia for use in Macintosh applications. Supports 256 colors, compression, and is used to save animation data, and was the predecessor to Quick Time.

★Suffixes of compressed files
In order to improve storage efficiency, many companies have introduced methods of compressing data and the corresponding software, the use of such files is mainly through the compression and unpacking software to carry out the main suffixes: *.zip, *.arj, *.rar, *.lzh, *.jar. There are also a number of specialized compression files, such as: *. ex_, *.dl_, *.d3_, *.cab and so on.
★Suffixes for Database Class Files
There are several types of suffixes in the environment of Dbase, FoxBase, and Foxpro series of software:
.ap Generate App .app Application Files

Backup files: *.bak,*.old,*.wbk,*.xlk,*.ckr_
Help files: *.hlp,*.chm,*.cnt
★Afterword
Users have to pay attention to the fact that in different operating systems, the convention of the suffix name will be different, for example, under Unix , *.p for Pascal language programs, *.z for compressed files, and *.tar for archived files. In addition, for very special devices, their drivers will also have special suffixes, such as the driver for the 3DS display card is *.exp. There are also certain companies for their own products also specify the file name suffix, such as the Founder's company's image layout files specify the use of *.grh (i.e. Graph).
The file name suffixes represent a certain type of file that will generally be generated and processed by a particular type of software. Only with some knowledge of these suffixes can you know what they are in the process of getting on the computer. Here with you to see some common types of suffixes, in fact, there are many types, it is impossible to speak all. As the saying goes, the master leads the door, the practice is in the individual, in the future you in the world of computers in their own turn to see it.
