Location of fileurns.cache and gnutella.net on Mac OS X
 

LimeWire 2.6.5 on Mac OS X 10.2.1.

On Mac OS X, LimeWire should store fileurns.cache and other files that are written to by the application (such as gnutella.net) adjacent to limewire.props, in the Library/Preferences/.limewire folder in the user's home directory. Currently, it is stored in the LimeWire application's folder. On Mac OS X systems set up to support multiple users, this folder is not always writable by all users, nor should it be: this cache is something that should rightfully be stored per-user alongside limewire.props.
