I use a FileUploader control in my application. I want to save a file to a specified folder. If this folder does not exist, I want to first create it, and then save my file to this folder. If the folder already exists, then just save the file in it.
How can I do this?

When you want to create a directory in a path that does not exist then an error message also display to inform the user. If you want to create the directory in any non-exist path or omit the default error message then you have to use '-p' option with 'mkdir' command.
How to create a folder if it does not exist in C#? For creating a directory, we must first import the System.IO namespace in C#. The namespace is a library that allows you to access static methods for creating, copying, moving, and deleting directories.
To create a directory if not exist in Python, check if it already exists using the os. path. exists() method, and then you can create it using the os. makedirs() method.
Create a Directory if it Does Not Exist You can use the Java File class to create directories if they don't already exists. The File class contains the method mkdir() and mkdirs() for that purpose. The mkdir() method creates a single directory if it does not already exist.
As others have said, use System.IO.Directory.CreateDirectory.
But, you don't need to check if it exists first. From the documentation:
Any and all directories specified in path are created, unless they already exist or unless some part of path is invalid. If the directory already exists, this method does not create a new directory, but it returns a DirectoryInfo object for the existing directory.
