why have the datafiles large free space and autoallocate new space even so?

 I have notices in recent weeks that the datafiles of the tablespaces allocate a large size of space (once 10 GB). I don't understand this behavior. The datafiles are autoextend and the increment size is 1MB but the datafiles increase although their free size at the end of the file is greater than 1MB.
I know that the extents are managed by Oracle because I use locally extend management with autoallocate.

Exist a relation between free space on a disk and autoallocate extents although this are two different levels?

Can you explain me why the free space at the end of datafiles are big  even so the datafiles grow?

Howdy, Stranger!
