Error code 10 at create folder

Question

i am developing a vi in which i have to create a folder in any drive(e.g D:\dataacquisition) than in data acquisition folder, i have to create date folder and name folder and then we need to create some files e.g patient's information, and like this different files in the name folder, i have shown this in attached vi, now the problem is this that when i run the vi for the first time when no folder has been made it runs ok with no error, but when i again run the vi with different patient name it shows Error code 10 at create folder, i know this error is because the same folder is already present, but the problem is this that when an error comes the new patient's folder is not created, i have tried several things but not able to avoid or remove this error, is there any way to remove this error or if there is any other option of creating folder in LabVIEW.
I am attaching the vi.

Thanks to every one, your suggestions helped me in solving my problem, although my problem is solved but i am having some more question

There is two ways you can do.
You can create the folder along with a time stamp including seconds so that your folders will be new always otherwise before creating the folder check whether it is already created or not. If already created skip the create folder function else create it.
Answer-Thankyou,for your suggestion, I tried Creating folder with timestamp including seconds, but it then shows error 1 which i think is formatting error, and yes the other option works well, by using the check if folder function vi works well.

Thanks your vi works well, but now i am having 1 more question 
I have also found 1 more other than check if folder exists by which error 10 is avoided but in that case name should be different, now what i want is when suppose i enter the same name in the suppose i want folder with name 'a' to be created and that folder is already present than what i am trying is that labview should ask weather you want to replace existing folder,or you want to delete,or you want to keep both files, delete and replace is easy to implement but although i am trying but if anyone knows the way that how we can keep both the files than that would be great help.
i am attaching the vi which is not complete yet, i am trying to implement some more extra points like keeping both the same files or if i want to replace.
