What is a FINGERPRINT file

FINGERPRINT files mostly belong to Notepad. FINGERPRINT files contain a cryptographic hash that acts as metadata, most often for Android apps. This file holds a string—a series of hexadecimal characters—that represents the file's digital fingerprint. Such a fingerprint helps ensure that the app's content has not been altered after it was signed.

Purpose: Stores a file hash used to verify file integrity.
Android Use: Serves as metadata during the app signing process to maintain security.
Access: Can be opened with any basic text editor, like Notepad on Windows or TextEdit on macOS.

FilExt.com note: This file plays a key role in app verification and security, even if its presence is not commonly noticed.
