InfoPath Dev

I would like to add File attachment control to my infopath form. Are there any limitation as to number of files attached to a single form and the size and types of the files attached? And any specific errors i would encounter using this control? Thanks

You will run into performance issues if your attachments are large, or if you have many files. Remember that the XML size will include the attachment's size. As to an exact size limit, it would depend on the environment/server.
