Upload directory

In my project I set upload directory to files/ (default value). When I upoad a file there will be created a subdirectory "userfiles" (I think this has always been the case) but furthermore there is created a sub to "userfiles" with the username of the person who uploads. Can I prevent this directory to be created ??? Any suggestions ?

The userfiles folder is for file manager extension, you need to use the username so that the files uploaded by user will not be mixed up for different users.

I see the point - has not always been like that, has it ?

My problem is I would like the files to be upoaded to the same directory - is it possible in any way ??
