[Android] where exactly are files stored?

ElizabethDobson

previously Zotero on android appeared to store pdfs in "Android/data" subfolders which were accessible (albeit it was somewhat difficult to share data between apps). Now with the latest version of Zotero the downloaded files here appear to be missing, yet I can still access them in zotero. Is the new location one that is inaccessible (even read-only) on an unrooted device? If not, what is the path where downloaded files are stored?

Misc information: I am using Android 13 and official Zotero sync

App storage is internal and isn't meant to be available outside the app, no. (The app also wouldn't re-upload a file that was somehow modified externally, since that's never supposed to happen.)

The mobile apps are designed to sync annotations with the desktop app seamlessly and efficiently using DB-based annotations, so we have no plans to support opening of PDFs externally beyond exporting. We'll be continuing to add features to the built-in reader in parallel with the desktop reader.

hmm，I see. for DB-based annotations, one should take the pdf is unchanged forever.

But Is it possible to add this feature for modifying PDF uploads? Considering the many users who want the external reader function…
