Hi! I am ACAD 14 user. I have about 10,000 files in directories/subdirectories. while i am searching files in the file dialog box i see their images in the small window. But i cann't see properly part's shape, because to many layers are visible. Would be useful to see only certain
layers in this window.
So does anybody now how to control layers
without opening files?
