SketchName_etch_paste_mask files?

When exporting a PCB view as PDFs or SVGs for etching, I see file names taking the format above have been exported, but the SVGs are all 0-byte (empty) files and the PDFs show a file size, but they are also empty.

Based on the file names, I assume they are meant to be used as protective templates when applying solder paste to the board. Correct ?? Should I just not worry about those files ?

Thanks in advance.
