Mac OSX writes out resource forks as hidden files alongside the data part of the file with names ._%s where the file is named %s.  This means that the database includes an awful lot of data that it shouldn't... moreover, it seems reasonable that it should exclude hidden files by default when scanning.  I can do some post-processing in sqlite3 to fix this (delete from objects where path like '%/._%') but that's less than ideal, and I dislike mucking with the database backend of a running application.

Could this be added?  Or would I be advised to send a patch in?

Hello. Is there a way to hide .AppleDouble directories when scanning ?
I find on the wiki pages:

Ignore dot files

* Description: Fuppes also indexes hidden folders, some users could not want this
* Patch: http://fuppes.ulrich-voelkel.de/forum/viewtopic.php?f=3&t=36#p205

But the link don't work.
