Hi! I'm sorry, I haven't used it, I could not help you. That was the reason I searched for you to a thread that might assist in finding an answer. I was hoping that would help you.

Shredding is just like deleting the file but before it is deleted the content is erased.

I have a File Shredder app and it uses 7 pass to erase the file and then delete it

File Shredder - BlackBerry World

By shredding it doesn't give you extra memory. It will just release the memory occupied by the file.

My concern with any app like this is that flash does not work the same as hard disks.

Flash controllers typically have something called wear-levelling that causes successive writes to the same address to get mapped to different physical locations in order to prevent premature failure of the flash.

I'm not saying these apps don't work, but unless they have low level access to the flash controller I don't trust them to be effective because the techniques used for file wipes via the standard file system API are not.

I use the file shredder app mentioned in the previous post and it seems to work well but I wasn't aware of this with flash storage.

This is admittedly a few years old, but still relevant.
