You should easily be able to download the .zip file to get the files inside: There are 6 main folders and most of the files are .rtf, and .png, but there is a .pdf in there, too. I say this because .rtf cannot hide macros so should be safe to open. I think image, .docx, and .pdf files can hide worms/viruses. so try to not open that those --unless the other files are just too real to be considered a trojan horse.
A guy just told me this might be safer than converting it on my own PC; Aspose Words Free Apps (https://products.aspose.app/words/viewer/rtf) Free Online RTF Reader/Viewer Online RTF Reader. Open, read, convert RTF documents for free.
we have differing opinions. Well, that never happens!
