However, if file F needs to be expanded, there are three options, since the space immediately following it is no longer available: Move the file F to where it can be Disk Defragmenter Windows 10 If you are a Windows user, then it is advised that you defragment, if you are a Linux or Mac user then it is said to not be as important.
