Hi all
I have a course a tutor is having trouble with. I am having a problem replicating the issue myself (I've tried quite a few times with no luck). The tutor has uploaded files to the course and later when she goes back into the course the files have disappeared. They are not in the file repository either.

I've done some internet research and not finding anything that helps. I am running Windows (don't be a hater), IIS. I have no problems like this with any other courses as far as I am aware.
I'm not sure if this helps but I downloaded a backup of the course to see what was there. I have trolled through the files.xml file and renamed all the resources to see what is missing etc. There are 35 instances of non existent files as follows:
<file id="85750"> <contenthash>da39a3ee5e6b4b0d3255bfef95601890afd80709</contenthash> <contextid>38926</contextid> <component>user</component> <filearea>icon</filearea> <itemid>0</itemid> <filepath>/</filepath> <filename>.</filename> <userid>$@NULL@$</userid> <filesize>0</filesize> <mimetype>$@NULL@$</mimetype> <status>0</status> <timecreated>1404163037</timecreated> <timemodified>1404163037</timemodified> <source>$@NULL@$</source> <author>$@NULL@$</author> <license>$@NULL@$</license> <sortorder>0</sortorder> <repositorytype>$@NULL@$</repositorytype> <repositoryid>$@NULL@$</repositoryid> <reference>$@NULL@$</reference> /file>
These records are also showing in the database.
One of the our Moodle managers had the same problem with the course so I'm sure its not a PEBKAC issue, but as I said before I can't seem to replicate it. I've tried uploading the same files, different files, renaming the files to remove spaces, brackets etc.
So my questions:
Has anyone had the same issue?
Did you fix it and how?
Can I clean the course and/or the database of these records somehow?
Can I delete the records directly from the file table?
Any suggestions on what I could try?
I have been thinking of rebuilding the course from scratch but it is a massive first year nursing course with many modules, glossaries, 75+ files, etc.
Any suggestions greatly appreciated. TIA
