All Files Viewer

Open common documents in one place

All Files Viewer is a document-reading and file-management app for Android. It is suited to anyone who wants one practical tool for opening PDFs and TXT files instead of switching between separate readers. The app focuses on getting documents open quickly and keeping basic file tasks close at hand.

Useful file controls

Alongside reading, All Files Viewer lets you manage documents from the same app. You can remove files you no longer need, check a document’s file path, and share PDF files with other people. The path display is particularly useful when you need to work out where a document is stored before moving on to another file task.

PDF protection and everyday reading

The app includes password protection for PDF documents. This gives you a way to lock important PDFs and unlock them when access is needed. TXT support covers simpler text documents, making the app useful for notes, plain-text records, and other files that do not require a full office suite.

All Files Viewer is listed in the Productivity category and is developed by Nullbyte Labs. With a 4.39 rating from 3,821 reviews and 5,000,000+ installs, it has found a sizeable audience among Android users who need straightforward document access. This is a utility for opening, checking, sharing, and tidying files—not an app built around features you will admire once and ignore afterward.
