Hello. I sent a notification about your question to the company employees, expect an answer from them here in the comments.

Hello Ciro,
could I have a clarification? The folder where you would like to store the attachments sent is a specific folder within the root directory of the website, or a folder elsewhere entirely?

Eric

Specific folder within the root directory of the website is fine.  But I'm not necessarily married to that.  Essentially, I want the receipts submitted from the form mentioned above are placed into a folder for convenient access.

Hello Ciro,
in this case you should be able to achieve this by creating a folder inside the root directory, and then setting this folder as the folder with write access in Parameters - Data management.
You will also need to check with your hosting provider to make sure the right access permissions are applied for this specific folder.

Eric

Great thanks I'll try this.
