in order to do this puzzle, you must have access to the following:
a file explorer to view file information
an image editor
...this is all you need, i think. most of the puzzle are riddle-based
this puzzle is special! the following restrictions are:
you will have to append (i.e. add) the next keyword to the end of the html name
the number of letters of each keyword will be one greater than the current segment number (except for 5-15)
for example, if the html file name is abc.html, and you're currently on 5-2, then it turns out that the keyword would be "xyz" and you would then navigate to abcxyz.html
if done right, 5-15's html file name should be 120 letters long
