w258306.mgr--------> which manager logfile is this  ?
t258277.mgr--------> which manager logfile is this  ?
c258292.mgr--------> which manager logfile is this  ?
s258291.mgr            --------> which manager logfile is this  ?
FNDSM258274.mgr  --------> which manager logfile is this  ?

FNDCPGSC253276.txt  --------> which  logfile is this  ?
