Update list folder during execution

[JakuPe]

Hi,

I need simple thing to my project. I would like run some VI if some file will be add to folder. 

I tried create List folder function with Path control (where can I choose source folder) and Array size. But if I add some file into folder then Array size is still same. Array size is update after rerun of VI. 

Some ideas how can I do that?

Thanks

You don't provide sufficient information. Do you run the "list folder" function at regular intervals on the same path or just once?

Can you attach a simplified version of your code?
