I have placed a “vue.js” file in the directory *\Anki2\user\collection.media
to use. And I have used it on my card actually. But when I use Tools - Check Media, Anki will think “vue.js” is a Unused file
ps: And I note the vue.js is not valid on the computer(Anki Desktop), but it is valid on the Andriod(AnkiDroid)
