I'm trying to print a particular web page to PDF using "Microsoft Print to PDF" on Windows 10.
Save Print Output As dialog comes up, I find that it's browsed to the (empty or near-empty) folder I want to store the file in.
I paste in the name, copied from near the top of the website I'm printing.
I press Save, and the dialog disappears, and everything proceeds with apparent success.
This is different from the situation where I've tried putting an invalid character like a colon in the filename, when an error message pops up with the file name and a message that "the file name is not valid."
However, when I later check the target folder, the file is not there!
I have all files visible (including hidden files and operating system files) so it's not that there's some messed-up file extension or property. I've tried this in an empty and near-empty folder so it's not just that I'm missing it in a long list. What's happening here?
