Using RushFiles, a file can either be locally present or on the server.

If the file is present locally, it is indicated by a green overlay icon.

If the file is not present locally, pressing the file will download it. This is indicated by a progress tracker:

You can cancel the download any time by pressing the “Cancel” option.

Once the download is completed the file is previewed. If the file format is not supported for preview, the "open with" iOS, or "share with" Android menu opens automatically.
