Can someone tell me if there is a way to turn of the decryption of files in Moodle after converting to Moodle 2.2 and above? The files, which are located in the Moodledata\filedir location. It is very time consuming going through all of the files and and almost impossible to associate them with a course, instructor and student. I migrated from version 1.9 to version 2.0. There was a backup done; but some of the files do not appear or have red Xs on them, stating that the "This legacy resource type (file) was not yet migrated, sorry." Please help.
The files are not encrypted. The filenames are based on the hash of the file contents. The mapping of filenames to where they are used stored in the database. Look at the File API Internals documentation for more details. If you have any further questions, they should probably be directed at the General developers forum and/or the Installation problems forum.
