FilePhile tends to solve person-to-person file transfer prolems with a piece of software so easy to use that anyone can use it and that uses the Internet the way it was intended: transferring directly rather than through some third party. Solving the file transfer problem means not having size limits. FilePhile has, for all practical purposes, none. You could theoretically send terabytes (1tb = 1000gb) of data with it though this would take a very long time with most net connections. File transfer sizes are limited only by your network connectivity, not by FilePhile.
