@neal-stone do you mean server side?

Yes to get the number of files in a folder and return it to a variable.  Checking if a file exists would also work.

@neal-stone using PHP it's quite simple:

Checking if a file exists:

Count files in a directory:

Also check the included FormSubmit sample app to understand how to send and get information from server side script.
If you don't want to use a Form Object, the same can be achieved by using neoAjax plugin commands.
