I have tried to download notes and attachment for a custom object under donot get the option to filter notes and attachment for a particular object.
- Login to http://dataloader.io with your login to Salesforce, it use SSO
- Click "New Task" and select "Export" button
- Select Attachment object, click Next
- You can select just the Body field, or with some fields, or all fields
- Click "Save & Run"
- Wait the process
Is there any other way to export the notes and attachment for a particular object
