Hi Lamya,

INCLUDETEXT fields aren't especially affected by file sizes though, as one might expect, performance degrades as the size increases - just as it does with ordinary documents.

Unless you're trying to create cross-references between the different source documents, everything should be fairly straight-forward.

If your primary motivation for combining these documents is for the generation of a composite table of contents, you should check out Word's RD field. With that, you can create a document that has as its only content your table of contents. RD fields, function in a similar way to INCLUDETEXT fields, but only for headings used in a table of contents. With RD fields, you first insert a TOC field, then an RD field pointing to the source document.
