In my institution we often use the same file names and will update content. It was great to just upload it to the file are and have all the links come through updated in one shot. I've been using the new files area for a bit and I can't seem to get the overwrite to work. Files are identical names and extensions but I end up with 2 files with the same name and I have to relink.
I'm just wondering if a) this is just me b) I'm missing something c) this is working as intended. If it is I'm definitely putting in a feature request.
