I am quite new in using JS, so I will try to be as specific as I can :)
I have a folder with 260 .png files with different country names: Afghanistan.
Afghanistan.
For linux/unix OS, you can use the shell syntax
const shell = require('child_process').execSync ; const currentPath= `/path/to/name.png`; const newPath= `/path/to/another_name.png`; shell(`mv ${currentPath} ${newPath}`);
That's it!
