Why not produce the fragmentation of files on Apple Macintosh computers and computers with Windows?
I wondered, as I have I never heard of having to defragment my files from Apple Macintosh. I got my Macbook Pro for a year and a half and never having to do any maintenance of this type. I wondered why people buy a PC when they could have that kind of stability. Oh, and please mark this question as interesting, if you own a Mac, we Mac users have to stick together in this war against Big Brother.
Optimization disk is a process in which the physical location files on a volume are "streamlined." Files and metadata are reorganized to improve data access time and minimize time to move the head of the Hard Drive. Files can be "fragmented" to over time as they are modified and saved, and the volume is filled with different parts of a single file stored in different locations in a single volume. The process collecting file fragments and putting them "back together", which is known as optimization. However, if an error occurs during optimization, as power loss, files can be damaged and must be restored from a copy of the security. What is needed to optimize? You may not need to optimize at all if you use Mac OS X. Here's why: 1 – the Hard Disk capacity is generally much greater Today a few years ago. With more space available, the file system does not need to fill all the "corners". The Mac OS Extended (HFS Plus) avoids reusing space from deleted files as much as possible, to avoid prematurely filling small areas of the space. 2 – Mac OS X 10.2 and later includes delayed allocation for Mac OS X Extended-formatted volumes. It allows a small number of missions that are combined into a single allowance within an area of the disk. 3 – Fragmentation was often caused by the addition of data continuously to existing files, especially with resource forks. Hard Drives caching faster and better, and the packet format for new applications, many applications simply rewrite the entire file every time. Mac OS X 10.3 Panther also automatically defragment files can slow growth. This process is sometimes known as "Hot-File-Adaptive-Clustering." 4 – Aggressive pre-reading and write caching means that minor fragmentation has less effect on perceived system performance. For these reasons, there is little benefit to defragmenting. Note: Mac OS X use hundreds of thousands small files, many of whom rarely visited. The optimization can be a great effort to win impractical. It is also the possibility that one of the files placed in the "hot band" for fast start-up system can be moved during defragmentation, which would reduce performance. If You Think You might need to defragment: 1 – Try restarting first. It may be useful and easy to do. 2 – If your disk is nearly full, and often modify or create large files (like Video Editing, but that the Council so if you use iMovie and Mac OS X 10.3), there is a chance the disks could be fragmented. In this case, you might benefit from defragmentation, which can be done with some third-party disk utilities. 3 – Another option is to backup your important files, erase the Hard Disk, reinstall Mac OS X files and backup. Tip: If you use iMovie on Mac OS X 10.3 Panther, and that FileVault is enabled, performance issues can occur if the project is in the encrypted home folder (including the desktop). See iMovie: Using FileVault can affect performance.
