Download IObit Smart Defrag Pro 12 full version. This program defragments HDDs and optimizes SSDs with TRIM, featuring Auto Defrag, Boot Time Defrag, and Game Optimize. It includes Thai language support and is easy to use.
What is IObit Smart Defrag Pro?
IObit Smart Defrag Pro is a hard disk defragmentation software designed to solve the problem of fragmented files scattered across different locations, which causes read heads to constantly jump back and forth. You can choose to scan the entire drive or target specific files and folders, and the program will reorganize the data placement for smoother access. Frequently used files are specifically placed in positions that the read head can access faster. One crucial distinction is that SSDs do not use traditional HDD-style defragmentation, as unnecessary data movement is harmful to the drive's lifespan. Instead, Smart Defrag utilizes the TRIM command for SSDs and features a dedicated drive categorization interface to suit the installed hardware.
If you don't want to remember when you last defragmented your disk, you can enable Auto Defrag or set up Scheduled Defrag to run at your preferred times. The program is designed to operate during idle times to minimize disruption to your active work. Meanwhile, Boot Time Defrag handles certain system files that cannot be moved while the operating system is running, such as startup-related files. These tasks don't need to be triggered manually every day; setting them up properly and letting the program run on a schedule is much easier. Additionally, it includes Large File Defrag for massive files and Game Optimize to organize selected game files without touching the entire drive.
The Pro version offers deeper customization than the free version, such as Intelligent Defrag, organizing large files, and a full Boot Time Defrag. It also provides more detailed disk status monitoring and automatic scheduling. If your machine has both an HDD and an SSD, you can choose separate management methods for each drive, eliminating the need to treat all drives in the same way. Tasks like deleting temporary files or cleaning up unused files are handled separately. CCleaner Pro works better when used together, but you should not confuse junk file cleaners with disk defragmentation software, as Smart Defrag focuses primarily on drive structure and data access.
