I need to slim down my moodledata folder and by extension the filedir folder used by Moodle repository but as the txt file in there warns me
"This directory contains the content of uploaded files and is controlled by Moodle code. Do not manually move, change or rename any of the files and subdirectories here."
So how do I go about finding orphan files or old files I can safely delete. My hosting system can identify the large file but is there an easy tool which will tell me where in Moodle they are used?
A few of the files are over 3GB in size but their filetype is text/generic because of Moodle's hashing of the filename and the last modified time stamp is fairly old but obviously I want to clean it up correctly not just delete and pray
Whats tools/methods are available to help me do this site wide?
