Now to the point...
This is an explorer shell context menu feature for Defraggler. So each time you click on some file, folder or drive icon, there will be "Defragment with Defraggler" option. Defragmenting your data has never been so easy!
How to use?
Install Piriform Defraggler first and then run my tool and just follow the instructions given by program.
SPECIAL NOTE FOR VISTA USERS:
You have to either disable UAC (not recommended) or manually set df.exe to ask user for administrator rights.
You can do this by right-clicking on df.exe file. Select Properties and then enable "Run this program as an administrator" under Compatibility tab. Not doing so will result in Defraggler failing to do it's job under Vista.
