How to hide a folder in sdcard in android

Question

I am developing an android application, It create some folders at starting of the application, which have images, video files and subfolder, i want to hide these folders and files at creation time. these folder should not be seen, when we access sdcard manually in device.

Answer 1

If you want to hide folder in Android or any Linux based system just add . as prefix to folder or file name.

However if you mount your SD card on Windows machine then these folders will be visible, with the . in front of the folder name, as a normal folder.
