Hi Michael and thank you very much for your ongoing support. I am a very newbie user so this may be a clueless inquiry… Exactly the title above.
I have tried to drag the file into a ProtonMail draft as well as a Gmail draft open in Safari; the renamed file will not remain so. It is a pdf “printed” from a web page in Safari, latest OS, EF.
HFNY and good luck with 2025 and 2.0!!
