The kids at school get a 900 meg network share. We remap their My Documents folder to it and (for the most part) it copies whatever they put in it over to the server without issue. I get emails when they exceed the 900 meg cap and it disables them from copying more crap but often times they aren't actually over. For example, if I select all the files and folders in this one persons share, then go to properties it shows 20 objects selected, nothing hidden and a total of 450 megs used. If I just try to view the properties on the folder itself it 20 objects in the folder, nothing hidden but shows 899 megs used. So where is the extra 449 megs coming from? The only solution I have is to give the students new shares, copy all their stuff into it and delete the old ones. That works, but it doesn't address the problem of invisible duplicate files. Any idea what is going on here?
