Encrypt your file from unauthorized access


If you don't wish to show your file to all the users in the computer or in a shared computer...encrypt the file by following the procedure below without using any software!!

   1. Click Start.
   2. In the Search box field type CMD and press Enter.
   3. In the command prompt, type cd… This will show you the C:\ Partition.
   4. Assuming that the picture you want to hide is under C:\  and that its name and extension is image.jpg  type: ren image.jpg image.txt (This is the syntax ren:(your file name and extension)(space)(your file name and the file extension you want to turn it to)
   5. The command above (ren image.jpg image.txt) will turn your image to a txt file. People trying to open such a  file will see unintelligible characters.
   6. Of course to get the picture back, simply type: ren image.txt image.jpg
   7. This trick works for every kind of file

Enjoy!!!!
