Access PDF metadata in OS level

[Tcd_2021]

When a pdf file is opened in Windows 10, where does its metadata (current scrolled positon, current page etc. ) stored in OS? Can we as a third party access these information?

If you're referring to the function of the application that restores the last view setting of a file then it's saved somewhere internally in the app. It is not a part of the file's metadata.

@try67 Thank you for the reply.  Is there a posibility to access those saved information related to last view setting from outside the application (as a third party) ?

There's no API for it. If you discover where it's saved, and it's in a format that can be easily read (like a text file, or a registry setting), then yes, you can do it.

May be that this information is stored in the registry of Windows.

Thank you.
Found the details in the registry in Computer\HKEY_CURRENT_USER\SOFTWARE\Adobe\Acrobat Reader\DC\.

The currently opened document informaton can be found in  Computer\HKEY_CURRENT_USER\SOFTWARE\Adobe\Acrobat Reader\DC\SessionManagement as well as the last pdf details found in Computer\HKEY_CURRENT_USER\SOFTWARE\Adobe\Acrobat Reader\DC\RememberedViews

Thanks for sharing it with us. It's good to know where these things are located...
