the only way to be 100% sure is to read optionally included readme files. If there is none, then sometimes the fonts themselves contain useful information and can be viewed with some special programs, like windows font viewer which, i think, comes pre-installed with windows. On Linux(with KDE) and Mac they are definitely present.
Many of them are shareware and some designers require you to share or send them a sample or pay a fee or send an email or...
Hope there is a file included(which also could be forged, but not likely)
Could someone please tell me where I can find the user License for the free fonts?
Can I use them, for example, for making commercial graphics etc., or do I have to purchase a separate license?
