The data stored in your hard disk may get fragmented...
Due to this you may face following problems:
1. Slow computer speed
2. Long hard disk access time
3. Reduced hard disk life
and many more...
To overcome these problems your must have some program which can defrag your hard disk...
Windows defrag program works well but it takes a lots of time and your computer gets busy for atleast 3-4 hours.
This program restarts your pc and runs defrag program only which optimizes defragmentation speed and also it automatically shutdown your pc after completion...
So just before going to bed switch it on and in the morning you'll find your hard disk defraged and pc shutdown...
