There is no automatic way to do it. You will need to read each file and then store it again encrypted.

Damn, OK. I could force the android encryption however I need to be able to truly encrypt certain files.
Thanks Erel.

Erel,

Would it be possible for you to give me a brief example on reading a file or copying then encrypting.. it seems everything I've read there is no tutorial or exact reference given.

Thanks again

You can read a file into a bytes array with the code in this post: http://www.b4x.com/forum/basic4andr...10012-writing-image-byte-array.html#post55567

Then there are several options. The simplest one is to use RandomAccessFile.WriteObject and save the bytes array.
