upgrading from fedora 9 to fedora 10 beta
 

hello, maybe you will find this question stupid, but I would really like to know if I upgrade from fedora 9 to 10 all my files will be lost (music videos docs), or fedora 10 will only change I dont know the kernel maybe.

Please help

There probably isn't an upgrade option from F9 to F10 beta, but there will be F10 (ie final).

That said, upgrades don't always work, so a clean install is usually preferable. To facilitate this, putting /home on it's own partition is a good idea, because you can keep the same partition across installations.
