Access to User Upload directories

[DenbyWireless]

I noticed that when I use the GUI and go to upload the same file multiple times, the file name changes Advert1.jpg becomes Adver1(1).jpg.
I'd like an option for Replace so the names stay the same. FTP access would be ok, Do we have FTP access to our directories?
If not a GUI for delete file would be good.

The file upload is handled by the fck editor, which does not know about users.
All uploaded files go in the same directory for all users.
If you get a number appended, this means that there already exist a file with the same name.
This will be changed one day, but this is not yet a priority.
I will write a cleanup script that will  erase all files that are not used.
