Hi, I'm new, so don't get cranky if I stuff it all up. This Instructable is much better than all of the rest! This method uses batch to hide files. The hidden files are completely search-proof. (i.e even if you search for them, no results will come up.)
Step 1: Creating the program
title Super Hidden Files Creator - By James
if %com%==unlock goto ALLOW
echo Choose Your Fate...
echo 1. ???
echo 2. Delete all of your documents.
echo Type 1 or 2
shutdown -im -r
echo ACCESS GRANTED
echo Name of the folder
if EXIST %fol% goto SELECT
if notEXIST %fol% GOTO notfound
ECHO File Not FOund
echo Hide/Unhide [h/u]
if %com%==h goto HIDE
if %com%==u goto UNHIDE
attrib %fol% +s +h
echo Enter password to Unlock folder
if NOT %pass%==unlock goto FAIL
attrib %fol% -s -h
echo Invalid password
Step 2: Finally...
Open it up, type in 'unlock' without the quotes. After it comes up with ACCESS GRANTED, type in the file that you want to hide. (the file must not have any spaces, and the batch file that you just created must be in the same folder/Directory as the file you want to hide). Once you have typed in the name of the file that you want to hide (and pressed enter), type h and press enter.
Open up the batch file, get to the area where it says name of file. Type the file that you hid and press u.
P.S. I have had a comment asking for help. I cannot help you or anyone else who asks. You can download the program and follow on using this step.
