NOTE: This article is for Mio's internal enterprise product. To learn about file sharing between universal channels, check out this article instead.

Just like messages, Mio receives files (such as PDFs and Word documents) as API events which it can translate and deliver across platforms.

Here's how cross-platform file-sharing with Mio works:

  1. The sender uploads a file into a space or channel, as usual, from their primary platform.
  2. Mio's service user works behind the scenes to route the file to all instances of the channel or space across platforms.
  3. If the sender has not synced their primary chat platform yet, the file will appear to be shared by your company's instance of the Mio app/service user (e.g. Acme Chat), and the name of the sender will be included in text only for context.

File types & 3rd-party hosting

All file types are supported for direct file uploads.

If your company uses tools like Box, Dropbox, Google Drive, etc. we recommend sharing a URL to the file, rather than using the service's integration, app, tab, or bot.


As with all content sent via Mio, your files and documents remain fully secure and private at all times. Mio is SOC 2 Type II certified and is committed to keeping your data secure. You can check our full security white paper for more information.
