very new to android. I want to secure thousands of individual documents on my phone. I would be ok with storing on phone password protected and having wipe capability but I don't seem to be able to create a directory or find a directory on the phone that I can store documents. SD card encryption programs seem to encrypt individual files and given the number of files I need folder level encryption. I can't believe there is not a solution. Am I slow or is there not a solution available.
