I am new to folder and file security for my laptop. Is there any good free software out there for locking files and folders from being accessed from others on my laptop. I am using Windows 7 and have a McAfee Security Centre.

Just to complement Fire Ant's post, I'll quote myself from a previous post:
TrueCrypt is well known, open source, free (both in terms of cost and in terms of freedom), and it works for Windows/Linux/Mac.
TrueCrypt is mainly a disk encryption product, however it can also work with a "container" file. Instead of encrypting a partition or disk, you just tell it to create a special encrypted file and store everything in there.
To work with TrueCrypt, you open the program, tell it to open the container you desire, enter the password and then a virtual drive appears on My Computer. Everything you place in that drive is encrypted on the fly, in realtime. You can access your documents directly from the virtual drive, you can open them there and you can save them there. When you open the document it gets decrypted on the fly; when you save it, it gets encrypted on the fly.
When you are done, just click a button on TrueCrypt to tell it to unmount the virtual drive -- no password necessary.
The beauty of this is that the protected files are never actually stored decrypted anywhere, just in RAM (unless of course you save a copy outside of the virtual drive). If the power goes down while the virtual drive is open, the data will still be encrypted. There is no "reencryption" process, so there is no need for entering your password a second time.
