+=head1 NAME
+
+SL::File::Backend::Filesystem - Filesystem class for file storage backend
+
+=head1 SYNOPSIS
+
+See the synopsis of L<SL::File::Backend>.
+
+=head1 OVERVIEW
+
+This specific storage backend use a Filesystem which is only accessed by this interface.
+This is the big difference to the Webdav backend where the files can be accessed without the control of that backend.
+This backend use the database id of the SL::DB::File object as filename. The filesystem has up to 1000 subdirectories
+to store the files not to flat in the filesystem. In this Subdirectories for each file an additional subdirectory exists
+for the versions of this file.
+
+The Versioning is done via a Versionnumber which is incremented by one for each version.
+So the Version 2 of the file with the database id 4 is stored as path {root}/0004/4/4_2.
