When I get a folder directory, I'm trying to write a program that modifies MD files in a folder in that directory.

1. Use the structure as is.
2. Modify the folder name and file name.
3. The MD file also modifies its contents.
4. The UI should appear.

Let's modify it to include the folder name.

Can this be implemented in javascript? It doesn't have to work on the web. I know JavaScript has limitations. Could it be Python? Or can you put a converter that can be manipulated from the web?

Tell me your tech stack or concept
