File iterating
You can try by running this code at your console:
deno run https://mega.js.org/demos/iterating-files-demo.js
import { getLoggedInStorage } from './logging-in-demo.js'
const storage = await getLoggedInStorage()
// Deletes all Thumbs.db files in the storage
// (second argument makes it recursive)
const thumbsMdFiles = storage.filter('Thumbs.db', true)
for (const file of thumbsMdFiles) {
// Set true to make it permanent
await file.delete(true)
}
