What should be removed from a document before filing?

Removing envelopes from a document before filing is the correct action because envelopes typically do not contain information relevant to the record and can obstruct the ease of retrieval and review of the actual document. Envelopes may also take up unnecessary space and could complicate the filing system, as they are not part of the content being retained as a record. By excluding them, records are kept neat and confined to only the pertinent documents, which enhances organization and accessibility.

In contrast, the other items mentioned, such as staples, page numbers, and tables of contents, may serve functional purposes. Staples help keep pages together, page numbers improve navigation within the document, and tables of contents provide an overview for quicker access to specific sections. Therefore, while maintaining the integrity and organization of records is critical, envelopes do not contribute to this efficiency.
