Listing files from a folder - second problem

I've posted this question here: but seemingly second questions in the same topic are not noticed. So i start new topic (related to ):

I have another problem with listing files from a folder.

I have 6 files in example folder: file1, file2, file3, file4, file5 and file6

I'd like to list only 3 of them (becaluse player has to complete them first in order to reveal rest). So the list should fool like this:

file1
file2
file3

Could You modify your example to work like this?

(I've tried to change event "for each file in XXX" to "repeat 3 times" but it doesn't select files properly.)
