How can you get a local filesystem link of an offline-accessible PDF file in Dropbox? I would like to get a link to a pdf file in my local Dropbox of my android. 
This is because I want to access the file by the syntax /local/system/something/file.pdf#page=116 in Internet Browser. 
I have the file as Available for Offline Use in Dropbox. 
I do not know if this stores the file as readable in my system. 

This would help me a lot because then I do not need to browse books at the very beginning of the file. The Dropbox browser is so limited that I cannot add there #page=116 in Dropbox's pdf browser so I need a link to the file in the filesystem.

It's in 

YourLocalStorage/Android/data/com.dropbox.android/files/uXXXXXX/scratch/Your/Folder/In/Dropbox/file.pdf


Note that YourLocalStorage depends on your mobile. For example, it is storage/emulated/0/ on some LG phones.

To access the file from your web browser you have to put file:/// before the given path.
