Windows Server 2012 R2 analyzes fragmentation and optimizes volumes as part of automated
Unlike Check Disk, which cannotĬheck and repair the operating system volume while it is in use, Optimize Drives can, in mostĬases, perform online defragmentation of any volume, including the operating system volume. The Optimize Drives utility, a tool for defragmenting volumes. Recovering files more difficult in case of serious disk error. This means it will take longer than usual to open and save files. Out across the disk, the fact that data is in different areas of the disk can slow down read/ Next file that is created and, as a result, part of a new file might be written to this newly freedĪrea and part of it might be written somewhere else on the disk.Īlthough the file system doesn't care whether the file data is on contiguous clusters or spread If youĭelete a file, an area of the disk is made available, but it might not be big enough to store the
So as you modify files, different parts of files can end up in different areas of the disk.
The file system uses the first clusters available when writing new data, This happens because files are written to clusters onĭisk as they are used. As files are created, modified, and moved, fragmentation can occur both within the volume'sĪllocation table and on the volume itself.
