Hello C++ Developers,

We have some really great C++ posts on LearnCPlusPlus.org with examples about Path Manipulation Routines that can be used in your C++ Builder Windows applications or your Mobile application, games, or may help to extend your C++ knowledge by the given different methods below.

If you are new to RAD Studio, we think these posts may help you much as a rapid introduction to programming in C++ and C++ IDE if you’re a beginner, all the way to the most robust, modern, and latest techniques for those more experienced with the language or for those who are perhaps wanting to expand their knowledge with the most up-to-date features, routines, and methodologies. The new RAD Studio 11C++ Builder 11, Delphi 11 are released with great new features and according to our tests, most of the examples from LearnCPlusPlus.org are working well with the latest RADS 11.

C++ Builder has a lot of specific methods in its SysUtils library that are included in VCL and FMX libraries. Some of these are grouped as Path Manipulation Routines which allow users to edit, extract, get and set drive name, directory name, file name, and file extensions. These methods are combined in Vcl.FileCtrlSystem.IOUtilsSystem.SysUtils libraries. These all methods are easy to use and easy to get or set file path strings in that operating system. These can be used with other component properties like FileName property of OpenDialog, SaveDialog components. We can also check drives, files, or directories if they exist or not in that given path. And we can combine two path strings as a new path string. C++ Builder is very powerful in these kinds of operations with the path strings.
