Why You Need to Open Multiple PDFs at Once

In many situations, you wish to open multiple PDFs at once. A few of the situations are listed below -

  1. If you are sending the same PDF file to different stakeholders with minor changes in the content of the PDF file, you will need to track the contents of the files. After all, the files are very similar to each other and only vary slightly in content. If you have to manually compare the contents of the files, it may prove to be a herculean task. This is especially true for very large PDF files. In this case, if you can open multiple PDFs side by side and compare the contents it will ease out the task.
  2. Often you need to read contents from a PDF file and check another very different PDF file for accuracy against it. In this case, it will be best to open multiple PDFs at once and check the accuracy.
  3. If you are in the academic world, you may need to ensure that students have not copied their assignments or projects. If the assignments are in PDF format and you can open the PDF files from multiple students at once, it will make this job easier.

In all the above situations, you may use the instructions explained in this article and open multiple PDFs at once with UPDF.
