Steps to Reproduce:

1. Connect a memory card or any external storage drive
2. Create a new file on that drive example sample.js
3. Try deleting the file (del)

Since it is on an external storage, moving it to the recycle bin surely is not allowed. The error is shown every time, instead of directly deleting it.

Reproduces without extensions: Yes
