Visual c ++ file extension Definition

[1]. APS: Auxiliary intermediate resource file for storing binary resources (which can accelerate resource loading ).

[2]. BMP: Bitmap resource file.

[3]. BSC: Browse information files. Generated by the browser information maintenance tool (BSCMAKE) from the original browser information file (. SBR). The BSC file can be used for quick locating in the source code editing window. You can remove generate browse info file from project options to speed up compilation.

[4]. C: Source code file written in C language.

[5]. CLW: File generated by classwizard to store class information.

[6]. CNT: Defines the structure of "contents" in the Help file.

[7]. Cpp or. cxx: Source code file written in C ++.

[8]. Cur: Cursor resource file.

[9]. Def: Module definition file for dynamic link library generation.

[10]. DLG: Defines the independent files of the dialog box resources. The VC project is not required, because VC generally places the dialog box Resources in the. RC file.

[11]. DSP: The project file generated by the VC development environment. vc4 and earlier versions use the Mak file to define the project. Project file, in text format.

[12]. DSW: Workspace file generated by the VC development environment, which is used to organize multiple projects into one workspace, similar to. DSP.

[13]. Exp: The output file generated by the Lib tool from the def file, which contains the output information of functions and data items. The link tool uses the exp file to create a dynamic link library. It is generated only when the DLL is compiled, and some information in the DLL file is recorded.

[14]. H,. HPP, or. hxx: Header files written in C/C ++ are usually used to define data types and declare variables, functions, structures, and classes.

[15]. HLP: Windows Help file.

[16]. Hm: In the help project, this file defines the correspondence between the Help file and the id value between the dialog box, menu or other resources.

[17]. HPJ: The help project file generated by Help Workshop is used to control the creation process of the Help file.

[18]. HPG: The project that generates the Help file.

[19]. ICO: Icon resource file.

[20]. Ilk: An intermediate file generated during the connection process. It is only used by the link tool.

[21]. Ini: Configuration file.

[22]. Lib: Library file. The link tool will use it to connect various input libraries to generate the EXE file.

[23]. Lic: User license file, which is required when using certain ActiveX controls.

[24]. Mak: Make file, which is used by vc4 and earlier versions to specify how to create a project.

[25]. Map: A text file generated by the link tool, which contains some information about the connected program and the image information of the execution file.

[26]. MDP: The old project file, which is equivalent to. DSP.

[27]. NCB: NCB is the abbreviation of "no compile Browser". It stores information for classview, wizardbar, and component gallery. It is automatically generated after the project is compiled. You can delete this file when the Automatic completion function fails.

[28]. OBJ: The target file generated by the compiler or assembler is the binary intermediate file of the module.

[29]. Odl: Source code file written in the Object Description Language. VC uses it to generate the TLB file.

[30]. Olb: A special dynamic link library with type library resources, also known as object library files.

[31]. Opt: Files automatically generated by the VC development environment to store various options in the workspace. The parameter file of the project about the development environment.

[32]. PBI,. PbO, And. PBT: Three files generated and used by the profile of the VC performance analysis tool.

[33]. PCH: Pre-compiled header file, large, automatically generated by the compiler when the project is created, which stores some of the Code that has been compiled in the project and will not be re-compiled when the project is created in the future, to speed up the entire compilation process.

[34]. PDB: A program database file is automatically generated when a project is created. It stores various program information to speed up the debugging process. Records Program-related data and debugging information.

[35]. PLG: Compile the information file, the error and warning information files during compilation.

[36]. RC: Resource definition file.. RC2: Resource definition file, which can be used in special cases.

[37]. Reg: Registry information file.. Res: Binary resource file. After the resource compiler compiles the resource definition file, the res file is generated.

[38]. Rtf: Rich Text Format (Rich Text Format) documents can be created by word or WordPad and are often used to generate help files.

[39]. SBR: The original browsing information file generated by the VC compiler for each OBJ file.

[40]. TLB: Ole library file, which stores the data types, modules, and interface definitions of OLE automation objects.
