GIF is the abbreviation of Graphics Interchange Format, which is the graphics exchange format. The file extension in this format is .gif

JPEG is an image format that supports a high degree of Compression

BMP is the abbreviation of bitmap, which is a bitmap image. Bitmap pictures store image information in a unit called "pixel". These "pixels" are actually some neatly arranged colored (or black and white) dots. If these dots are slowly enlarged, you will see that each "pixel" is filled with its own color. These "pixels" are neatly arranged. When arranged, it becomes a BMP picture, with a .bmp (.rle, .dib, etc.) extension.

A complete list of file suffixes (a must-read for novices)

What is a file name suffix? Speaking of file names under the Windows work interface, you can simply do whatever you want, such as: The work of an editorial department in 2000 plan. The file name can be directly expressed in Chinese, and the length can be up to 256 characters, which makes it clear at a glance. However, in the Windows environment, there are a large number of file names similar to CALENDAR.EXE, GAMES.GRP, etc. in the installed software. Why is this? It turns out that these file names are based on the file name naming rules of the DOS environment. File names under DOS environment: Under DOS, the file name adopts the 8+3 structure, that is: a file name with a maximum length of 8 digits, separated by a decimal point, followed by a suffix name with a maximum length of 3 digits, such as: READ.ME, SETUP.EXE , Generally speaking, Chinese characters are not allowed in file names and can only be composed of letters, numbers and some symbols. For example, READ.ME in Chinese means "read me", which prompts users to read the contents of this file before using the software to obtain more prompt information. More importantly, DOS requires the use of suffix names to distinguish various files. The most common thing to encounter under DOS is executable files. There are two types of suffixes: *.exe and *.com (* here means any file name). They are compiled from assembly language or other high-level languages. A file in which the program is compiled and run directly under DOS. Sometimes, due to the many functions of the software and the small memory, it cannot be loaded into the memory at once and there may be ovl files with the same file name, such as ws.exe, ws.ovl. There is also a file that can be run directly, *.bat, which is a batch file. There are many commands or executable file names in it. It is mainly used to improve work efficiency. The most useful one is Autoexec.bat. This file will be Be automatically executed (automatically execute means Automatically execute in English). Another type 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 certain non-standard devices such as mouse, expanded memory, etc., such as mouse.sys ,himem.sys. For unified management, a config.sys text file is specially provided to automatically load these necessary device drivers at startup. Once these files are accidentally deleted or renamed, or are infected by viruses, they will directly cause the system to malfunction. Not normal. Files generated by word processing under DOS originally do not need a suffix, but people often use *.txt to represent them (txt is text). Supported by all platforms and all applications. For the convenience of management, people can also use their own names as suffixes to indicate that they are text files created by themselves. For example, many of the articles I entered are *.mcj, so that users can restore the original files as soon as possible if they accidentally delete them. Many word processing systems provide an automatic backup function for the original file. For example, when I edited JIHUA.MCJ for the second time (JIHUA: planned Chinese Pinyin), the system would first copy the original file to JIHUA.BAK.

When using word processing software with special formatting functions, such as WPS launched by Mr. Qiu Bojun in his early years, the suffix will be .wps to identify text files generated by WPS. When using word processing software to edit high-level language programs, the suffix is ??usually the first three letters of the corresponding language (for example: *.BAS means BASIC language source program, *.PAS means PASCAL language program, *.FOR means Fortran language program, * .C means C language, *.ASM means assembly language program). The following types of files are often attached to the executable file: *.HLP is the help file (help), *.CFG is the configuration file (config), *.DAT is the data file (data), *.LOG is the log file ( log) and *.TMP are temporary files (temporal).
