Analyzing a drive
You can use Defraggler to defragment any hard drive, but it's not always necessary. Hard drives tend to get fragmented over time, as old files are deleted and Windows uses these scattered free areas to write portions of new files.
If you're working with a relatively new PC, if you've defragmented your drive recently, or if you don't use your PC much, you may not need to defragment. Use the Analyze feature to determine how fragmented your drive is first.
Note: Alternatively, you can also search for specific types of files to defragment.
