Lock My Folder is an Android application developed by SmallCat Media that allows you to hide your important folders and files from prying eyes. With this app, you can keep your personal files locked and secure, ensuring that friends who use your phone don't see them if they browse through your file manager or any other application.

The app lets you lock unlimited folders that can contain folders, photos, videos, audio, and all kinds of files. It works with both your device's memory and SD card, and you can access your locked files with a PIN or fingerprint. Lock My Folder also has a built-in video and audio player, and you can share your locked files directly on any social media platform.

One unique feature of Lock My Folder is that it captures a photo of the intruder trying to access your files with the wrong password. Additionally, the app does not show up in the recent apps list and automatically quits in the device's sleep mode. If you forget your password, the app can send it to your registered email ID. Overall, Lock My Folder is a useful app for anyone who wants to keep their personal files and folders secure.
