I recently created a Flask Web app on Heroku where in I take some file from the user do some processing and return the processed file to the user. However I do not want to retain the files after processing for a very long time ( say I want to keep it just for 3 hours). What should I do ?

Heroku has a temporal file storage. Files are deleted periodically and thus temporary storage of files is bad. If you want to learn more, go here: How to use heroku's ephemeral filesystem

The idea is every time a dyno is restarted, all temporary files are destroyed.

If you want to go around this, use amazon s3: https://devcenter.heroku.com/articles/s3
