The SimplifyPath method is a static extension method provided by the SandboxSystemExtensions class. It is used to simplify a given file path by resolving any redundant elements such as ".." or "." within the path string. This can be particularly useful for normalizing paths before performing file operations.

To use the SimplifyPath method, you need to pass a string representing the file path you want to simplify. The method will return a new string with the simplified path.

Example usage:

string path = "/a/b/../c/./d";
string simplifiedPath = path.SimplifyPath();
// simplifiedPath will be "/a/c/d"
