The problem with the double quotes which might need explanation is two
fold:
First, like I said before, some (and most on PCs) files don't support
quotation marks, or other random characters in their file names such
as /, *, ", etc... Another similar programming phenomenon is a space.
Take for example when you go to a web page or image that has spaces in
the file name, these spaces are replaced by an ampersand (&) or a plus
sign (+) in order for the browser to read your file.
Second, ASCII characters (which is what the "Char(34)" referred to)
are from the American Standard Code for Information Interchange.
Basically, each character has an ASCII value assigned to it which you
can refer to in most programming languages and the computer will
understand it as the character it's referencing (built in variable
definitions if you will). When we're trying to print something such
as a file name, in order to use symbols which the programming language
uses to differentiate other things such as comments, we can use the
ASCII value so that it doesn't get confused as to what we're trying to
output. You can look up the ASCII table online and see that the
printable characters start at 32 and work their way up, the quotation
happens to be the second on the list giving it the ASCII character
code 34.
Hope this helps with some of your scripting questions!
