Start by creating a new stack and drag on a button for our script and a field to hold our list of files.

The following lines of code are the key items we need for this particular task. The 'defaultfolder' is where LiveCode looks when you perform file or folder requests. So if we set the 'defaultfolder' to where our files are we will be able to read them very easily.

set the defaultfolder to tFolderPath

The second key line of code required is this one. It will return a list of all the files in the 'defaultfolder'.

put the files

Edit the script of the button by selecting it (1) and clicking on the code icon in the toolbar or right clicking and choosing Edit Script. Paste the following script into the script window (2) and click Apply (3).

on mouseUp
	# Pops up a dialog box letting the user select a folder
	answer folder "Please select a folder"
	
	# Exit this handler if the user click cancel on the dialog
	if it is "cancel" then 
		exit mouseUp
	end if
	
	# Set the default folder to the folder selected by the user
	# (this is stored in the 'it' variable
	set the defaultfolder to it
	
	# Put a list of all the files in field 1
	put the files into field 1
end mouseUp

When you switch to run mode (1) and click on the button (2), a dialog should popup asking you to select a folder (3). All the files in the folder you select will be listed in the text field (4).
