Hello Luana,

Here's how you could approach this situation on your account:

Listing tickets that have attachments: Unfortunately, Zendesk does not directly support filtering tickets by the presence of attachments. However, by using the Tickets Comments API you can programmatically iterate through all tickets' comments to check if they have attachments affiliated with them. This operation may require a substantial number of API calls and could be bound by rate limitations or impact performance, so be careful when setting this up.
Removing attachments: Deleting tickets will remove the associated comments and attachments in the process. However, since you want to keep the ticket and delete the attachment, I'm afraid it's not directly supported by our API. A potential workaround could be downloading the necessary information, deleting the ticket, and then creating a new one with the retained information but without the attachments.
Regularizing the use of file storage: Here are a few additional solutions to manage your file storage:

Automatically delete old tickets: You could set up an automated process that deletes tickets that are older than a certain date.
Outsource file storage: Instead of storing files directly, you can use third-party apps to send files via a link. The actual files can be stored in a cloud storage solution like Google Drive, Dropbox, or Box.

Keep in mind that any changes to data in your system should be done cautiously, ensuring all privacy regulations are met and important data is properly backed up or archived before deletion.

I hope this helps.

Remove an attachment from a ticket with a closed status.
