# PDFAttachments Object (IPDFAttachments Interface)

This object represents a collection of PDF attachments of a document (PDFAttachment objects). It contains methods for getting the number of attachments in the collection, accessing a single element of the collection and iterating through the collection. The collection is accessible via the [FRDocument](/fine-reader/engine/api-reference/document-related-objects/frdocument) object.

* The indexing of ABBYY FineReader Engine collections starts with 0.
* The foreach statement in C# (for each in Visual Basic .NET) can be used to manipulate the collection.
