Hi,

Why is the difference between a regular folder and a dropbox folder?

If there's no difference I think you only need to filter which file extension do you want to read. The problem could be if you want to read all of the extensions except *.ini or this particular .ini file. There´s no a direct way to do it, I mean, with a dropdown list or a checkbox, but you could write an expresion to determine which files you want to process.

Hier is a great example.

Kind Regards.
