Using the filter, you can select all orders or customers which:
- have attachments, also from letters
- have files attached only to the card
- are without any attachments
New column "Files/Attachments" will show how many documents were added to the order card or the customer card, and how many attachments were sent in letters bound with them.
You can also remove all files from all or only certain orders / customers. Just select the necessary ones in the list and then choose "Remove files" in menu of actions.
