Just when I was preparing a blog related to spatial 3D modeling, I stumbled upon the following problem:
After opening the PDF file named " Spatial 3D Modeling_Operation.pdf " in this figure, its title changed to another name in the PDF reader:
Yes, the original PDF file name changed to " The name "Class Planning Book".
Seeing this new name, I immediately thought of it—this is a Word I wrote a long time ago in school, and the title is this "Class Planning Book"; and I can still remember it because of the original "Class Planning Book" Word The format, typesetting, and cover of the file are better, so many learning and working documents directly use the "class planning book" Word file as a template, and modify the content on it; and my "spatial three-dimensional modeling_ The original Word file of the ".pdf" file was also modified based on this "class planning book" Word file template.
So, open the "Properties" of the original Word of the "Spatial 3D Modeling_Operation.pdf" file:
As expected, this Word has the title "Class Planning Book". Then the problem is clear: I used the PDF conversion that comes with Office 2019 Word, which retains the original Word file "title" information by default; and for some PDF readers (for example, I use Foxit in this article), its When displaying the name of the PDF file, it is based on the "title" information of the PDF file. Because of this, the problem at the beginning of this article has arisen.
Then, delete the "title" information of the original Word file as blank and re-export it as a PDF file:
open it with the same PDF editor, and the problem is solved.
I discovered this problem for the first time, so I quickly recorded it to alert myself.
In particular, it should be noted that it seems that some PDF readers do not use the title of the original Word file as the name displayed after the PDF is opened. For example, I have been using Jinshan's PDF reader before, and it seems that this problem has not been found. It means that it may be different from the Foxit that I use now in displaying the PDF name. Then we need to pay more attention: there is a problem with this kind of PDF file that you can only see by yourself. If it is a more important PDF-for example, the interviewer will be sent to the interviewer to modify it with a template, which has been named "XXX resume.pdf The name displayed on the PDF reader of our own computer is no problem, but the interviewer installed other PDF software, but the name displayed on the interviewer’s computer is “fresh and elegant workplace resume template”. , It's very embarrassing.
