Verify and create folder if not exist

Hello everyone
i'm doing an internship and i need help with labview programming. i'd like some help. the subject is that i've created a array containing data from an excel file in one column and the second column contains the worksheet to which the data belongs. then i've created a list of folders in a array using the list folder function. these folders have the same names as the data. the problem is that i'd like to compare the two, list folder and column 1 which contains the data and see if it exists i'd like it to be moved to a folder containing the name of the excel tab if not i'll create it.
