Scheduled tasks question

[The Old Timer]

I understand that by using 'scheduled tasks' you can have programs run
automatically at some predetermined times. If you have several partitions
can you have things like defrag & disk cleanup done to all partitions?
Would you have to schedule each partition separately? Since you don't know
how long it will take to defrag the first partition would you have to guess
as to when to schedule the second partition to defrag or can the 'scheduled
tasks' program do the jobs in sequence or simultaneously?

 

[Mark L. Ferguson]

the task can run a *.bat file with commands that wait for completion

--go.bat--
start /b /WAIT defrag c:
start /b /WAIT defrag d:
start /b /WAIT defrag e:
--cut--

Disk Cleanup could be scheduled at logon or anytime
