Insert File Script that opens a folder location

[MariaAux]

Hi there,

I store all the files I am going to insert into my database in a specific folder. I created a script to insert a file into a container field, and I want the script to open the 'Insert File' window browser to that specific location each time. However, it seems that when I select the option 'Select Source File' in the options, I have to put the location of a file, not a folder. i.e.

file:../../Lesson Plans/Materials/Topics/

Is there any way that I can have the script 'Insert file' to a specific location on my C:/ each time?

Thanks so much and I appreciate all your help.
