.AHL File Extension
What is an AHL file?
Configuration file used by eMule, a peer-to-peer (P2P) file sharing program; replaces eDonkey, an earlier file sharing client.
The AHL file can be used to limit the maximum numbers of sources that the client can connect to at one time. (Select Options→Connection, then Max Sources→File, and enter a value for "Hard Limit"). eMule will search and connect to sources until the Hard Limit value is reached.
AHL stands for "Auto Hard Limit."
