very good to security you files.
I used PGP desktop to make ENCRYPTED VIRTUAL DRIVER ( E.V.D).
Note: PGP desktop is not a freeware you need to buy the software
After you instal the PGP desktop duble click to open the main window
Step 1: E.V.D File
the PGP desktop will mount the image file for you after you crate the pgp disk file
but if don't just double click to open ou left click to menu.
Step 2: Passphrase
Step 3: New Virtual Disk Show on My Computer
Step 4: Copying the Files to the E.v.d
Step 5: Unmouting the Virtual Drive
Step 6: Extras Files on Cd
Step 7: Burning the Files on Dvd.
i have lost many dvds trying to burn big file with nero, i recommend you
to use the avs cd dvd creator is freeeeeeeeeeeeeeeeeee and work 100%
this is the link for you download
Step 8: Final Step
if you like to burn another dvd you don't have to create another pgp file just mount the pgp file on your computer again and replace the files in side the virtual drive.
to use de virtual drive just mup the cd on your dvd drive and mount de pgp disk file
sory for my por inglish .
