Move database-flies in 10g

Hai,

 i try to get all database files onto another media.

from E:/ to F:/ (backslash doesn´t work)

it works well, instead of the control files.

i changed the path to the control files in the pfile.

i can start the database with the pfile.

but a standard - startup doesn´t work.

can i change the spfile to get a standard startup?

i hope you know what i mean.

thanks a lot!
