How to move files using C++?

In C, you can use the std::filesystem::rename function to move files. This function requires two parameters: the source file path and the target file path.

How to move files in C

Moving files is an operation of transferring files from one location to another. without creating a copy. In C, file movement can be easily achieved using the std::filesystem library.

Header file inclusion

Before using std::filesystem, you need to include the header file:

#include <filesystem>

File movement

To move files, you can use the std::filesystem::rename function. This function requires two parameters: source file path and target file path.

std::filesystem::rename("source_file.txt", "target_file.txt");

Practical case

The following is a practical case of how to use std::filesystem::rename to move files:

#include <filesystem>

int main() {
  std::filesystem::rename("old_file.txt", "new_file.txt");
  std::cout << "File moved successfully." << std::endl;
  return 0;
}

Note:

• If the target file already exists, std::filesystem::rename will overwrite it.
• If the source and target files are on different file systems, std::filesystem::rename will fail.
