Defrag defragmentation of Vista system

        In a disk partition, files are scattered to different places on the disk instead of being continuously stored in contiguous clusters of disks. And because during the file operation, the Windows system may call virtual memory to synchronize the hypervisor, which will cause each program to frequently read and write to the hard disk, resulting in disk fragmentation. The system has been running for a long time. As users continue to delete and move files, disk fragmentation will occur, and Vista's running speed will be seriously degraded. The disk will cause the data to be arranged in an inconsistency. When the hard disk accesses the data, the head needs to search for data in multiple locations instead of continuous reading and writing, which will inevitably cause the performance of the system hard disk to degrade. How long does it take to defragment a piece of time? This needs to be judged based on the frequency of personal computer data deletion movements. Defrag can help users analyze whether the partition needs to be defragmented, so that users can be more clear when they need to be organized, when not needed. Finishing it? Let Windows Vista tell you. In the Start menu - Search box (or Win+R to launch the Run dialog), type cmd in the open command prompt dialog, enter defrag g: -a (note G The latter half of the colon and space), so Vista Disk Defragmenter will analyze your disk partition G, after analysis, you can get the prompt whether you need to defragment the disk, (the whole analysis process requires high frequency read hard disk, please do not perform other Operation, the analysis process is about 30 seconds, please be patient and wait for the end). In the above figure, you can see the prompt "You don't need to defragment the volume process". If you need to sort it, then we will sort the disk partition G. (The finishing process takes about 20 minutes. According to the disk fragmentation and disk size, you need to read and write the hard disk during the finishing process. Please do not perform other operations or suddenly restart the computer, power off, etc.), we input defrag g: -v ( Pay attention to the colon and space after the g), you can perform the defragmentation of the G disk: These two commonly used parameters must be useful to everyone.
