Bot looping through directory for mp4 specific file - node.js

Question

I'm trying to make a bot where it would upload a mp4 attachment with a specific command. What i wanted to know is if there was a way where the bot would cycle through the directory for the certain file instead of me writing like 600 lines worth of code.
const fs = require('fs');
const { Client, MessageAttachment } = require('discord.js');
const config = require('./config.json');
const { prefix, token } = require('./config.json');
const client = new Client();
const { MessageEmbed } = require('discord.js');
client.commands = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
for (const file of commandFiles) {
const command = require(`./commands/${file}`);
client.commands.set(command.name, command);
}
client.on('ready', () => {
console.log(`${client.user.tag} is now online!`);
client.user.setPresence({status: 'idle'});
client.user.setActivity('My Stokeley Playlist 🌙', { type: 'LISTENING' })
});
client.on('message', (message) => {
const { content, author, channel } = message
if (author.bot) {
return
}
const embeds = {
[`${prefix}snip kratos`]: {
title: 'Kratos',
attachmentPath: './snippets/kratos/Kratos.mp4',
},
[`${prefix}snip johnny bravo`]: {
title: 'Johnny Bravo',
attachmentPath: './snippets/Johnny_Bravo/Johnny_Bravo.mp4',
},
}
const embed = embeds[content]
if (embed) {
const { title, attachmentPath } = embed
channel.send(
new MessageEmbed()
.setColor('#ffb638')
.setTitle(title)
.setDescription('Sending 1 snippet...')
.setTimestamp()
.setFooter('SkiBot')
)
channel.send(new MessageAttachment(attachmentPath))
}
})
here's my current code, I'm trying to find an easier and cleaner way to go about this.

I think you have already used this in a part of your code
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
So try this
const musicFiles = fs.readdirSync('./snippets/kratos').filter(file => file.endsWith(".mp4"));
