Part of the Xfile System, Xfind searches dropped files for keys you specify. When no key is given, Xfind sums block use, file sizes, and use of resource forks.
Xfind performs recursive searches: refine your search key, and then drop the search results back on the Xfind window.
Used in combination with Xfile and Xscan, Xfind makes it finally possible to list and sum up virtually anything on your disk.
