ERES has no definite limitations on document formats
annexes to the registration module and files. We must keep in mind, however, that
certain features of the service such as authentic copy, notification
electronic or the signature holder, are limited to documents in pdf format.

In relation to the weight of the documents, making use of the functionality for
attach documents from ERES screens, although there is no limit
specific weight, files over 30MB are not recommended
weight

In the file entry mode attached to the records and files that
incorporates the webservices of the service, documents that do not pass can be attached

As for the nomenclature of the documents, you should always follow the following
pattern, always in capital letters and avoiding spaces:
