When in my library i have folders shared (green field and a tickmark) and open "UDP port for peer connections.." (which should not be necessary in all cases), every user can find any of my files when using Search tab and typing for example: filename
?

Someone complained he can't browse my shares and i was thinking if Fopnu has some limit on download slots, since 5 users already downloading from me simultaneously. So here is my question from the title. Thank you
