file size in terms of percentage of original file size.

Maximum File Size section helps determine the maximum

size of a file. To determine the maximum file size for datafiles, we have two options:A. Unristricted file growth: Allows the file to grow till

the disk space is not full.B. Restrict file growth: Allows you to specify the file
