An iDrum file is a file with the .idrum extension that contains all channel settings, patterns and song. It can optionally contain the sample files referenced by the channels (larger file, but more portable -- great for sending your loops or song to people over the internet) or it can simply store references to files stored elsewhere on your hard drive (smaller .idrum file, but will force you to 're-find' files should the sample files be moved or deleted.
