I do quite a lot of stuff with downloading files, moving files, deleting files, and i find that i spend at least 3 days every month or so to do the following:
1)CCleaner. Kill excess files and reg clean-up
2)Disk Clean up. Remove more excess files.
3)DataRecovery. I use this to permanently remove all those ‘deleted’ files.
4)Full on disk check. The kind that makes you restart to do, goes into the blue screen of checking.
5)Defrag. So all the file stuff is faster.

This routine works, but it can take up to 3 days.

steps 1-3 take (on a bad day) up to one hour.
step 4 on the other hand can take up to 1-2 hours.
step 5 can take 1/2 hour, to 3 hours.

Now, I do steps 4 and 5 when im at school or at night. but it still can take 2-3 days to do all of the stuff.

Is there any way i can schedule check disk and defrag?

Thanks.
