Multitasking in Files on iPad Pro

Yes - using native capability, you simply open two instances of Files...

1) Start by opening your Files App - and then navigate to, and open your first PDF.

2) Now, swipe-up from the bottom edge of the screen just enough to reveal the dock (don’t flick, as this will return you to the last used home screen; likewise, don’t swipe-up to the middle of the screen and pause, as this will invoke the task switcher).

3) From the open dock, drag the Files icon to either side of the screen - to open a second Files window in Split Screen mode.

4) In the second Files window, navigate to your second PDF.

You should now be looking at two PDF files - side by side 🙂

Hope you find this helpful.

My pleasure to help.

You can even open third App instance - using a Slide Over window! With the release of iPadOS, multi-tasking is finally useful on iPad.
