The app is for recovery of deleted PDF files from the internal memory or SD card. If you lose PDF files because of some reasons, there is no need to worry, the app will help you restore your PDF documents.

To restore your PDF files, you need to connect your device to the internet. If the device is not connected to the internet, the app will display a message that the document can not be restored.

If you restore the document successfully, it will be downloaded to your mobile phone. If you are not connected to the internet, the app will download the document to your mobile phone and then restore it.

If you find that the document is not restored, you can send feedback to the developer to help improve the app.
