Use the System Disk Monthly script first, then the Weekly script weekly.
If the files are on a separate partition, use the Data Disk script on this one.
Sorry Im not sure if I understand...
I have to use the System Disk Monthly script only for the first time ?
Or I have to run three scripts one after the other ? If it's this, Do I have to schedule 3 tasks ?
Sorry but it's the first time I use MyDefrag...
