LightRocket Media Manager has been designed to accept a very wide variety of file types. This includes photos, videos, audio files and other file types such as PDFs etc.
Indeed the number of file types we support - including all the various video codecs - are too numerous to list here. Feel free to contact us if you wish to verify the compatibility of a particular file type.
Please note, too, that some file types like Word or Excel documents don't preview easily so they might be represented as an icon indicating the type of file but without displaying any readable content. But once you download one of these files they will be readable. of course.
