Everything you run in this Window will be run with administrator rights. The "-a" parameter tells the defragger to perform a fragmentation analysis. The "-v" option tells it to be verbose in its report.

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. For example, to defrag all your Vista volumes regardless of fragment size and when there's less than 15 percent free space, enter this line at the command prompt and then press Enter:.

The utility will display a report on the selected volumes prior to beginning the defragmentation. Unfortunately, defrags run from a command prompt aren't any faster than those conducted via the graphical interface.

That's the biggest advantage of specialty defrag programs such as Auslogics' Disk Defrag, which is much speedier than the defragger in Windows. The fact is, Vista's automated defrags were doing a great job of keeping my disk space nice and compact. I didn't notice much of a performance improvement after I manually defragged my Vista PC, but the defrag did wonders for my ancient XP box, which I admit I had neglected to defrag for many months.

The other day, I was talking to a guy who wanted a PC but didn't want Vista. He asked me how long he would have to wait for new PCs running Windows 7.

When I told him that such systems were still several months away, he indicated that he'd buy a machine from a company that let you "downgrade" Vista to XP. I didn't say anything, but part of me thought he was crazy. Browse All Windows Articles. Windows 10 Annual Updates. OneDrive Windows 7 and 8. Copy and Paste Between Android and Windows.
