TrueCrypt | I encrypted the second disk, now the files do not open, how can I change the letter for all files?

Question

TrueCrypt

For a trip around Russia, I decided to encrypt the second disk of the laptop in truecrypt, if it is stolen, then the shish will get it, but now the files do not open.
How to change the letter E everywhere to encrypted G for all files? Because manually clicking on the properties and changing to the desired letter is not good at all.
