When you install Symantec DLP 15.x, it asks you where to install the program, you can specify D drive for the location. But then it starts putting the ProgramData to C: Drive where there is not enough space, and constantly competes with the operating system and that is sub-optimal.
Should provide for the ability to specify a different location for ProgramData folder instead, so that program volitile data is stored in a different drive, instead of C:\ProgramData\Symantec\Data Loss Protection\15.1
