7650 Remove default ringtones

[hmartires]

I'm trying to release some KB's in my mobile. I want to delete some of the default ringtones.
I have tried with a programa called "eFileManager" and I can access the files in drive Z. However I can't delete it.
Any one can help me on this one?

Thank you in advane for your help.

Z is your ROM drive, you can't delete anything from it, there's no point in trying anyway coz you can't store anything on it either, without reflashing your phone..
Cheers
