If you have not read part one I suggest starting there. It is at TrueCrypt – Free OpenSource Encryption for Everything!
We are now going to mount our encrypted drive for use. This is simple but something that is needed to complete this howto.
Start TrueCrypt and you will see the following -
“Select File” this is the file container we created before. This can be located on your hard drive such as c:secure.files, an USB/Flash drive, a CDR, or your DropBox. If you are using a “somewhat” hidden file such as a dll as described before. Make sure that “Never Save History” is checked. 
Now select “Mount” so that we can put in our 20+ character password.
We will need to put in our password. Please do not cache the password in memory. I have not figured out why that would even be an option but it is. If you created a device with a KeyFile this is where you will also add it. For this I used no KeyFiles. The “Mount Options” are also available.
If you are mounting a secure file and want to make sure it does not get damaged. Select “Mount Volume as read-only”. The second option is to “Mount volume as removable medium”. This will make the new drive show up as a USB drive. This is used because some programs will not run from a removable media. For instance “Family Tree Maker” will not run from a removable drive. Oh yea you can run programs from these drives. I personally run my financial software from one so that I have another layer of security.
So once this is done select “Ok” and “Ok” and your done. Go to My Computer and you should see the drive mounted. You can now use it just like any other device on your machine.
Remember I use this for DropBox if you are looking for an invite just ask here at
DropBox, now that is how you do it!
The good folks at DropBox have given me even more invites!
