It seems like I always have the hardest time trying to do
the simplest things. For instance in the code snipet below the

Now, the next step would be to generalize this stuff in case you need
it again in the future:
change-suffix: func [
{Changes the suffix of the string and returns the updated string.}
string [any-string!] The file, url, string, etc. to change.
