Supplementary Files

Role: Extra files for an article — supplements, figures, slides, etc. — separate from the main PDF.

Save them in the same Main library (or secondary library) as your article PDFs.

Main file vs supplementary file

Type	Naming	Example
Main file	PMID.pdf	`33301246.pdf`
Supplementary file	PMID + `_` + text	`33301246_supplement.pdf` `33301246_supplfigure1.jpeg` `33301246_tableS1.xlsx`

Use the PMID, then an underscore _, then a short label (letters, numbers, or both).

Examples:

Pub-Xel links these to the same PMID as the main article.

When you open Inspect Window, supplementary files appear under Supplementary files, separate from Main files.

You can open or export them individually, or together with the main PDF.

Keep the main article as PMID.pdf (e.g., 33301246.pdf). Use _ only for extra files so Pub-Xel can tell them apart.
