Downloadable response file remains in OpenAI storage

[dhoegerlETM]

Describe the bug
We have a pro-account and tested the feature of file-upload and download of a generated response. In our connected OpenAI account we found out that the uploaded files are cleaned afterwards correctly but the generated response files (with purpose type "assistants_output") remain in the file storage, which we consider a leak and therefore a bug.

To Reproduce
Steps to reproduce the behavior:

1. Activate file upload in your chat bot.
2. Start a chat
3. Ask a question to generate some output file, e.g. an Excel table.
4. Await the response, download the result.
5. Go to your OpenAI account and check the storage area "files" for the generated file
   => a) it is still there and b) is contains the whole linux-path as name instead only the part after the last slash.

Expected behavior
Output-files from OpenAI should be cleanly removed after the response as well.

I added to my backlog a feature to clean OpenAI account after X days.

It will remove files added after X days.
