VffInstall.log file size 93 GB file

Backup exec 22

VffInstall.log file size 93 GB file. file location - C:\Program Files\Veritas\Backup Exec\RAWS\LOGS 

i followed this article - Backup Exec VffInstall log size keeps increasing (veritas.com). logging is disabled, most of registry entries are not present. Hence no point adding a zero. What is the role of VffInstall.log file ? Is this only present on BE22 ? Do veritas guys have a solution or a fix for this? VffInstall.log is causing trouble for us on daily basis. 

Is there a workaround like move this file to G:, F: etc ?
