It reads to me like you are still getting used to (and perhaps a little confused by) the Linux directory structure. As a user, your top level user directory (where personal files and sub-directories are located) is represented by ~/ (eg /home/david). So, then ~/Download is equivalent to /home/david/Download.

One last observation - during the install I noted that the exe files were referred to as ,deb (AMD64). I have an intel i5 chip. Is there any problem? - it seems to work very well!
Debian (.deb) packages are not executable - they are a package file format (or container if you like) for installing software. They usually contain executable files, libraries, and documentation as part of a program or library being installed. These are usually installed via a package manager, or via the command line using apt-get (advanced packaging tool).
Windows often uses self-extracting executables to do this job, so that's the difference in a nutshell.[/quote]
