Check A Directory From Access

Hello creators,

I have a little problem and it is creating and checking directories.

In my database I have a form, on it you can see a record of a project. This project has a keyfield called projectno.
On this form there is a button to create a directory with the projectnumber. So far so good. (code example: MkDir ("C:projects444323")

My problem:
If the directory for some reason already exist the code stops and gives an error.

Now I want to create some code that checks if the directory already excist so than I can skip making the directory.

Thanks for the help!!!!!
