Short answer. The entire pleading. Section 7 of Rule 10 requires that when a pleading is amended, a new copy of the entire pleading — incorporating the amendments, indicated by appropriate marks such as underlining or strikethrough — must be filed, not just the amended portion or a separate list of the changes made.
What the law says
When any pleading is amended, a new copy of the entire pleading, incorporating the amendments, which shall be indicated by appropriate marks, shall be filed.

The whole document, not a redline excerpt
Section 7 is direct on this point: when any pleading is amended, a new copy of the entire pleading, incorporating the amendments, which shall be indicated by appropriate marks, shall be filed. A party filing an amended complaint or answer needs to submit the complete document as it now reads with the changes incorporated — not merely a supplementary page listing what changed, and not the original document with a separate errata sheet attached. This applies whether the amendment adds a single paragraph, drops a cause of action, or rewrites several pages; the filing obligation does not scale down just because the actual change is small.
Why the amendments must be marked
The requirement that amendments be indicated by appropriate marks serves a practical purpose: it lets the court and the opposing party see, at a glance within the single consolidated document, exactly what was added, deleted, or changed from the prior version. This is typically done through underlining new text and striking through deleted text, so the amended pleading functions both as the operative document going forward and as a visible record of what changed. Without those marks, the reader would have to compare the old and new pleadings line by line to spot the difference, which the marking requirement is meant to make unnecessary.
Practical consequence for drafting an amended pleading
Because the entire pleading must be refiled in this consolidated, marked-up form, a party amending a complaint or answer needs to prepare a complete replacement document rather than a short supplemental filing. This keeps the case record clean — anyone reading the amended pleading gets the full, current version of the party's claims or defenses in one place, along with a clear view of what was revised. It also means the opposing party's responsive pleading should be drafted against the full amended text, not against the original pleading plus a mental note of whatever changed. Section 7 binds whoever is doing the amending, plaintiff or defendant alike, and it does not carve out an exception for a minor or one-line change; the obligation to refile the whole marked-up document applies uniformly regardless of how small the actual edit turns out to be.
