Navigator window allows you to work with files and folders inside the trading platform's /MQL4 or /MQL5 directories. They store trading robots, indicators and scripts, as well as source code files and other data for programming on MetaQuotes Language. Press Ctrl+D or execute Navigator command of the View window or in the Standard toolbar to show/hide the window.
The window resembles a file manager displaying folders and files as a tree list:
A similar structure is displayed in the Navigator window of the trading platform. For example, if you create your indicator in the MQL5\Indicators\MyIndicator\ directory, you can launch it in the trading platform from the same directory.
To view the folder contents or open a source file for editing, double-click on an appropriate element in the Navigator. To re-locate a folder/file, select it and drag to a necessary directory while holding the left mouse button (Drag'n'Drop).
External changes to directories and files (via Windows Explorer) are also displayed in the Navigator window.
A separate Navigator tab is designed for managing projects. All used files are arranged into various categories:
- Dependencies – include files. These are files with the source code, which are used in the project. For example, dependencies may include standard library files.
- Headers – header files. Such files contain custom identifiers, macros, structures and other constructions used in the project.
- Sources – source code files of the project.
- Resources – resource files, such as images, sounds, etc.
- Settings and files – sets of input parameters (*.set) and other files.
