How to defragment the hard drive windows vista

If you want a report on drive D: or some other drive, substitute that drive letter in place of c:. Be aware that defrag may tell you that you have no fragmented files even if you have some. On NTFS partitions, the reporting function of defrag does not consider fragmented files with fragments greater than 64 MB as fragmented.

If you need truly detailed information, you may have to consider getting a third party defragmenter such as those listed on the Free Defragmentation Utilities page on thefreecountry. The "-r" option tells the defragmentation utility to treat files that are fragmented with 64 MB fragments or larger as though they are not fragmented.

This partial defragmentation is the default for "defrag", and it's the only way the GUI defragmenter in Vista works. You can also force the defragmenter to defragment everything. That is, even if the file fragments are larger than 64MB, the Vista defragmenter will still attempt to put the file into contiguous sectors.

To do this, run the defragger with the following options:. As you have probably have guessed, "-w" tells the Vista defrag tool to do a full defragmentation.

All file fragments will be consolidated where possible. You will still not get any feedback as to the progress of the defragmentation with the command line tool, just as you did not with the GUI version. However, at the beginning and the end of the defragmentation, "defrag" with the "-v" option will give a report, much like the old Windows XP GUI defragmentation utility.

Again, though, it will not report fragmented files with 64 MB fragments or larger as being fragmented. With the command line version of the Windows Vista defragmentation utility, you have at least a modicum of control over the defragger, and some information about your hard disk file fragmentation. If you need any further details or fine control over the defragmentation of your hard disk, you may have to consider a third party defragmentation tool.

To defragment a particular drive, say C:, type: defrag c: -v -r The "-r" option tells the defragmentation utility to treat files that are fragmented with 64 MB fragments or larger as though they are not fragmented. To do this, run the defragger with the following options: defrag c: -v -w As you have probably have guessed, "-w" tells the Vista defrag tool to do a full defragmentation.
