Hi, I wasn't probably clear enough. I run a Garbage Collection process  from
a batch file every minute (the method is contained within the same
application that will adds to the repository), so after restarting the
application the GarbageCollection will run and the files will be deleted. If
I add a new item to the datastore AFTER I have restarted the the application
this new one is NOT removed when Garbage Colelction first runs, but the old
one is. 

See below for file listings you asked for.

Euan
