The following entries are for deleting the logs created by Acronis True Image 11 and Disk Director Suite 10. The settings below are specific to Windows Vista, but should be fairly easy to modify for other operating systems:
ACRONIS TRUE IMAGE 11
FileKey1=%programdata%\Acronis\TrueImage\Logs|*.log
FileKey2=%programdata%\Acronis\TrueImageHome\Logs|*.log
ACRONIS DISK DIRECTOR SUITE 10
FileKey1=%programdata%\Acronis\DiskDirector\Logs|*.log
