How to see files and file structure on a deployed Heroku app

My client app that is deployed on Heroku allows the user to upload images onto Heroku. I wanted to test out a change I made to delete images, so I need a way to see the state of the folder structure on Heroku to ensure the images are being deleted successfully of the file system.

I tried -

$ heroku run bash --app <appName>
~$ pwd
~$ cd <path to images folder>

but I only see images here that I uploaded along with the app, not what was uploaded through the client app.

What am I doing wrong?

Solution

I can do with this commands

heroku login
heroku run bash -a APPNAME
$ cd app

APPNAME is the name of your Heroku application And in the folder app are your files.

When you finish your commands and want to return to your terminal you can write

$ exit
