Shared directory
From AMule Project FAQ
When a directory is shared through aMule, all of its content (files in it) is made available to other eD2k/Kademlia clients.
To share a directory in aMule, go to Preferences -> Directories and check the box next to the directory you want to share.
By default, sharing a directory does not result in its subdirectories (the directories inside that directory) being shared. If you want to share a directory recursively (that is, the files in a directory and all of its subdirectories), dobule-click the folder icon by the directory name.
ATTENTION: Be very careful which directories you share or you could wind up accidentally making your sensitive data (passwords, address book, private stuff, etc.) available to the rest of the world.
