In Excel-Word Interop, how do I use the File Object after using the Name function to rename it? - vba

Question

Overall objective: create an Excel-based file converter that interops with Word, changing several built-in document properties, header/footer text & pics, watermark, and file name. The new attributes/text/file paths are found in cells. After changing all these attributes, et al, the file is to be copied as a regular .docx to a new Output folder and also exported as a PDF to a separate PDF Output folder. Optionally the files in the input folder will be deleted after the other steps are completed.
Specific problem: After I rename any of the files using the Name function, the File Object (I'm using File Scripting Object) loses its reference to the old file (since it's renamed), but does not pick up on the new, renamed file. After renaming the file, I would like to make a copy of it into the word document output folder; then, with the original, I would export it to the PDF output folder. Finally, I would either delete it or leave it alone, depending on an optional boolean.
I have attempted to re-assign the File Object with the new file, but this doesn't seem to be possible, and nothing else in its properties or methods makes sense to use.
