Rewrite File- Gallery & Browser

the news query for the count all files in subdiretories with access rights looks awesome :D
From a vocabulary with 3000 terms from 20 sec. to 100 milli sec.

"SELECT COUNT(*) AS count FROM {node_access} AS na
INNER JOIN (
SELECT fn.nid AS nid FROM {file_nodes} AS fn
WHERE nid IN (
SELECT nid
FROM {term_node} tn
INNER JOIN {term_data} td ON tn.tid = td.tid
WHERE tn.tid IN (". implode(',', $alltermids) .")
)
)
res ON res.nid = na.nid
WHERE res.nid $grants_sql AND grant_$op >= 1"

needs testing by community
