Creating new ccp and h files

Hello Everyone.
I and new to PlatformIO IDE.
I have used many IDE’s to write code in the past. I cannot work out how to create a new CCP file and their matching header files. All I can find is a way to search for an existing file. Do I need to use a separate text editor to create the files to start with. If so it seems quite clunky

I solved the problem. The way the file name box was turning red as i typed in the new file name keep putting me off and making me think I was doing something wrong. Pressing Enter mad it create a blank file for me to add code.
