To hide files on a blackberry is not a big deal. But people go extra miles, spend time, cause unnecessary problems like mistakenly locking up apps. To hide files is very easy and you don't need apps to do it. I'll take this in 2 ways, follow these simple steps :
METHOD 1: (Hiding from being visible in the media app):
1- Open media
2- Press menu and scroll to explore. Select
3- On the desired file, press menu and scroll to 'rename'
4- Rename the file extension e.g 'jpg' to anything you like. You can use 'jpgZ'
This way the phone asks you if you're sure of your action as it may 'render your file unusable'. Just choose 'ok'. By doing this, your files will not be visible in the media player.

To hide files and folders
1- Go to media
2- Scroll to the desired file or folder
3- Press 'menu', scroll to 'properties' and click
4- Scroll down and tick 'Hidden'
5- Close.
This method hides your files and folders from even the inbuilt explorer.
NOTE: Try to backup your file before trying this.
