ALinkCreator
From AMule Project FAQ
ALinkCreator (also known as ALC) is an application which will give you the ed2k link for any file you ask it for. It can support all available ed2k links optional values and is very fast at hashing files.
It is available in two formats: the GUI version (windowed-style interface) named alc, and the command line version (text-only interface) named alcc (corresponding to alc command).
Guidelines about its usage are available in this article.
