I am currently interested in code for searches for the
existence of either folders or files. If the current month
is January, I need to search a given path to check of
a sub-folder named "January" exist. If the "January"
folder is not found, I will need to create that subfolder.

My first question is how do test if a folders exists?
Second, if it doesnt exist, how do you create it???

Once it is determined that the desired folder exists
(or was just created), I will need to search that subfolder
for an arbitrary file. My last question is, how can I
determine if a file exists in the folder so I can open it??

Thank u all
