EncFS.plugin is a plugin for MacFusion. Using Valient Gough's EncFS FUSE based file system EncFS.plugin allows easy and user friendly access to encrypted mount points in user space. What does that really mean? A cool folder, where anything you put in it becomes encrypted, without the need to "reclaim disk space" as you would with sparse disk images.
Finally it is very easy to install, also there is an even easier way :
Get information about Macfusion, and in the opeing window, in the Plugins section, just add EncFS.plugin !
And relaunch Macfusion.
It works very well !
