Only inactive files should be transferred to the State Archives. However, sometimes new documents are generated and need to be added to a file previously transferred to the Archives. In these situations, the creating agency can interfile the new documents into the file at the Archives.

What is an interfile?

An interfile is a document that was never previously transferred to the Archives but that is being sent to the Archives to be added within a file that is already in the custody of the Archives. Please note that the Archives can only accept interfiles if the folder in which it belongs is in the custody of the Archives. If we receive individual documents to be added to files which have not been transferred to the Archives, we will return the documents to the Agency of origin.

What is not an interfile? - Complete Files

Please note that interfiles are not complete files. For example, if you previously transferred cases numbers 1-9 and 11-20, case number 10 is not an interfile. When you are ready to transfer case number 10, you should treat it as any other new transfer to the State Archives and not send it as an interfile. View Procedures for new transfers to the State Archives.

What is not an interfile? - Refiles

Refiles are records that the Archives had in its custody, then returned to the agency at the agency's request, that the agency is now returning to the Archives to put back in the same box. If a record was previously in the custody of the State Archives, it is not an interfile. View Procedures for sending refiles to the Archives

Preparing Records for Interfiling
