If you allow these files to be created by other text editing 
applications, filtering by Mac file type is out..

If you want to maintain the ".txt" extension, filtering by extension likewise.

The only practical approach I see off the top of my head involves 
building a custom answer file dialog stack and filtering the detailed 
files for the selected folder:

	put the detailed files into folderContents
	repeat for each line fileInfo in folderContents
		get URLDecode(item 1 of  fileInfo) -- itemDelimiter 
should set to comma
		if offset("Slof",it) <> 1 then next repeat
		-- process or build list of "Slot" files here
	end repeat
