Well first of all we need to make sure we have a file created. So go into My files and create you’re folder. Give it a name that you will recognise. You then need to put whatever data you want to hide into here. So for example if it was photos taken with you’re camera, you go into the DCIM folder, then Camera folder, select the photos and then move them in to the folder you created.
Now you have all the data in the folder. So here is the important bit. You are now going to rename the folder that you just created, but all you’re going to do is put a full stop (period for u Americanos!) at the beginning of the name. So for example if the folder was called Party, then rename it so that it is called .Party
You will now realise that the file has disappeared. Don’t worry! It is still there. It’s now just hidden.
Now by default on the Samsung Galaxy S3, hidden files are not shown. So if you want to now display hidden files, here’s what to do. Go into My Files, press the options button on you’re phone and select settings. Check the box that says ‘show hidden files’ and then press the back button.
You’re file that you created should now be displayed. Simples!
Thanks for reading, hope it helped!
