The VeraCrypt volume you mounted
functions exactly as a normal Windows drive. You can
open files situated in it,
navigate the file system in the volume,
copy files from outside into the volume or
create files directly in the volume. An
important note on how to use the volume is that internal files that you would like to keep encrypted should
never be taken out of the volume. Whatever you need to do to the files, it should happen
inside the volume. If this is not done, then information on the files you have stored in the volume might be recorded and kept by Windows on unencrypted parts of your system.
NOTE: Files that you
generated outside of the volume, but that you then encrypted,
need to be securely deleted. You can look up the
VeraCrypt manual for more information on how to do so.
