Anyway, enough blather on to the good stuff!
Step 1: Get WinRar
Step 2: Archiving!
First step: Select all the files you want protected and right click on one of them. (the file names will still be visible so if you don't want that to happen then go ahead and put all the files into a new folder and then right click the folder and proceed) Click on "Add to archive . . ." you'll notice a little stack of books next to it (ain't they fancy!?).
A window called "Archive name and parameters" will pop up and may look a bit overwhelming at first but be still my enthralled readers all will be explained in due time!
Step 3: More Archiving
-Give it an inconspicuous name
-Select a format (probably want zip if you're moving it from computer to computer)
-You can play with the other options to suit your needs but I nearly never use them myself.
Step 4: Finish Archiving
-Click "Set Password. . ."
-Fill in and confirm a password in the new window and click ok
Now Click "OK" in the main window and you're done!
Step 5: Final Notes
One thing to take into consideration: as soon as you start encrypting, password protecting, or otherwise securing files visibly the more attention you start drawing to them. . . .it's sort of like getting a portable safe: a thief simply steals the whole thing and opens it back at his hideout.
