I currently use True Crypt to encrypt maybe 50 files on my Hard Disk.  My problem is I want to back up these 50 files to an external hard drive, but not if the files will be un-encrypted on the external hard drive.  

What should I do ?  I

Make a truecrypt volume on the external. In fact I think you can just copy the truecrypt file if you don't want to make the whole thing an encrypted volume

If it's only TrueCrypt files, all you need to do is copy over the files in their encrypted state.

If I open up the file from my external drive how does true crypt know what password to accept...do I need to copy over my true crypt settings file that gets created every time I create a volume.. Thx

No settings file is necessary... if in doubt, copy over the encrypted file and stand-alone truecrypt app to external drive; plug in another PC, run truecrypt and decrypt the files-- verify all OK.

Note: Make sure your volumes are dismounted prior to copying initially.

x66,

I guess my confusion is when I first used TrueCrypt I created a container called MyContainer that is found under MyDocuments.  It is a 250 GB Container.  When I mount the volume it is mounted  to the Z: drive.

If I dismount the Z drive as you suggest my files (the 50 excel, word, and other important documents) are no longer visible.  Should I be copying the container from my PC Hard disk (My documents) to the external hard drive and not the files themselves as the container is really the repository for the files ?

Yes, exactly right. Copy the dismounted container file in it's encrypted form to ensure data privacy.

be sure to dismount the file before you copy it, then just drag the .tc file to the external unit.
