What is content://cz.mobilesoft.appblock.fileprovider/cache/blank.html?

This strange-looking link refers to a file stored temporarily in your Android device’s cache. Let’s break it down:

content:// — This is a URI scheme used by Android to access shared data securely between apps.

cz.mobilesoft.appblock — This is the package name for the app AppBlock made by a developer from the Czech Republic (CZ).

fileprovider — This lets apps securely share files using content URIs rather than file paths.

cache/blank.html — This is a temporary file, likely a blank HTML file used for loading content or blocking content.

So what does it mean?

It means AppBlock is storing a blank web file inside your cache folder, probably for content filtering, blocking pop-ups, or redirecting URLs.

Why Does This Show Up on My Phone?

There are several reasons this file path might appear:

1. AppBlock Is Installed

If you’ve ever installed or used the AppBlock app to block notifications, focus on work, or limit screen time — this file path is a normal part of its operation.

2. Installed By Another App

Some Android apps bundle AppBlock features or use its SDK. So even if you didn’t install it directly, it might be part of another app.

3. Cache Viewer or File Explorer App

Some apps like file explorers or antivirus scanners display internal URIs, showing paths like this.
