How Can Boost.Filesystem Simplify C Directory Creation on Linux?

Creating Directory Trees with Ease in C on Linux

Creating multiple directories in C on Linux can be a cumbersome task, especially if you want to ensure their existence before saving files. However, with the help of Boost.Filesystem, the process becomes effortless.

Consider the following scenario where you need to store a file named lola.file in the directory /tmp/a/b/c. However, the intermediate directories (a and b) may not exist. To address this requirement, we can leverage the create_directories function.

#include <boost/filesystem.hpp>

int main() {
    boost::filesystem::create_directories("/tmp/a/b/c");

    // Save `lola.file` in the newly created directory
    //...

    return 0;
}

The create_directories function automatically creates all non-existent directories in the specified path. It returns true if new directories were created or false if all directories already existed.

Using Boost.Filesystem simplifies the directory creation process, making it straightforward to organize your file system structure.
