Have you ever faced a situation where you have to hide photos, documents or correspondence from prying eyes, but you don't know how to do it effectively? In this article, we will analyze all the current ways to put a password on a folder - from built-in functions to third-party solutions with encryption.
It's important to understand that password protection and hiding folders are different processes, one involves blocking access without entering the code, the other involves removing it from the visible file structure. We'll look at both approaches, including nuances for different versions. MIUI (12 to 14) and Redmi models (Note 10 to Note 13 Pro)+). You will also learn which methods work without root rights and where they are mandatory.
1. Built-in tools MIUI: "Private Album and Protected Folder"

π‘
If the option "Secure folder" is not in the settings, update MIUI check the firmware region (the feature may not be available in global builds for some models).
Limitations of the method:
- β Does not work with documents (.pdf,.docx), APK-file-file.
- β When resetting the phone to factory settings, the data in the protected folder is deleted without the possibility of recovery.

6. Hiding folders through.nomedia: pros and cons
The.nomedia file is the standard way to hide media files from being scanned by a gallery and music players. It doesn't password-protect a folder, but it excludes its contents from being indexed by system applications. MIUI It does not require additional software.
