As the title, are there any plugin that allow us to upload any file type such as docx, txt ... ?
You should be able to do this by enabling Allow users to upload regular files in the ACP, and leaving the allowed extension list empty, or just putting in the extensions you want to allow.
Allow users to upload regular
I hope that you do realise that allowing all file extensions is rather dangerous without extra precautions.
Leaving the allowed extensions list empty is something I would strongly advise against.
thank you so much
