FILESIZE parameter in DATA PUMP

Question

Hi All,
As per the data pump syntax if we define FILESIZE paramter is create dmp files with that mention file.
But My question is if I ignore FILESIZE parameter, How oracle define the size of parameter.
I am creating dpexp with following syntax for dpexp file. It creates dmp files with name SCHEMA.ENV.080410..p1*%U*.dmp with 1,2,3 etc.
IT creates the files with different size.
JOB_NAME=SCHEMA.ENV.080410..p1
DIRECTORY=dump_dir
DUMPFILE=dump_dir:SCHEMA.ENV.080410..p1%U.dmp
LOGFILE=SCHEMA.ENV.080410..p1.explog
PARALLEL=16
CONTENT=ALL
EXCLUDE=INDEX,CONSTRAINT,TABLE_STATISTICS
TABLES= TABLE NAMES

TABLES= TABLE NAMESAs you defined PARALLEL=16, Data Pump will create 16 process and each process will write to it's own file, that's the reason why you get different sized files
