Optimizes the allocation of space used by virtual hard disk files, except for fixed virtual hard disks. In this article Syntax Optimize-VHD [-Path] [-Mode ] [-AsJob] [-Passthru] [-CimSession ] [-ComputerName ] [-Credential ] [-WhatIf] [-Confirm] [] Description The Optimize-VHD cmdlet optimizes the allocation of space in one or more virtual hard disk files, except for fixed virtual hard disks. The Compact operation is used to optimize the files. This operation reclaims unused blocks as well as rearranges the blocks to be more efficiently packed, which reduces the size of a virtual hard disk file. To use Optimize-VHD, the virtual hard disk must not be attached or must be attached in read-only mode. The compact operation can succeed without reducing the file size, if no optimization is possible. Examples Example 1 PS C:\> Optimize-VHD -Path c:\test\dynamic.vhdx -Mode Full Runs the compact operation in Full mode. (If the VHDX-format file is not attached as read-only prior to the operation, it will default to Prezeroed mode.) Example 2 PS C:\> Optimize-VHD -Path c:\test\dynamic.vhdx -Mode Retrim Runs the compact operation in Retrim mode. (If the VHDX-format disk is not mounted as read-only prior to the operation, running the cmdlet returns an error.) Example 3 PS C:\> Optimize-VHD -Path c:\test\dynamic.vhdx -Mode Quick Runs the compact operation in Quick mode. (If the VHDX-format file is not attached as read-only prior to the operation, it defaults to Pretrimmed mode.) Paramet...

Best Disk Defragmenter? Your computer works hard to do the tasks you ask of it, shuttling data to and fro. Sometimes it… For those of you unfamiliar with the problem of file fragmentation, a quick—and quite simplified—primer is in order. Files are stored on a hard drive in blocks of data. The larger the file, the larger the number of blocks it is composed of. As your operating system accesses files, moves files around, and so on, data blocks are not always arranged in the most effective manner. Imagine it like a messy office where as you opened file folders from your file cabinet you frequently placed documents from inside all over the room. You have a great memory, and you can find all the pages from each folder again if you need to, but you waste a lot of time just moving around looking for them. In a perfect system the blocks of data that compose a file would be in the immediate vicinity of the file header, and your operating system would waste no time at all looking for the other pieces of the file. As it stands, however, on a badly fragmented disk the data can be scattered in pieces across the entire platter of the hard disk. The following defragmentation applications are specialized tools which will help you optimize your hard drive. Continuing with the analogy of the file cabinet, a defragmenter is the helpful assistant that comes in and alphabetizes all your documents in the appropriate folders and file drawers for you. If you're in the mood to dig into the more ar...

Fragmentation makes your hard disk do extra work that can slow down your computer. Removable storage devices such as USB flash drives can also become fragmented. Disk Defragmenter in Windows rearranges fragmented data so your disks and drives can work more efficiently. Disk Defragmenter runs on a schedule, but you can also analyze and defragment your disks and drives manually. To do this, follow these steps: To defragment your hard disk • Open Disk Defragmenter by clicking the Start button . In the search box, type Disk Defragmenter, and then, in the list of results, click Disk Defragmenter. • Under Current status, select the disk you want to defragment. • To determine if the disk needs to be defragmented or not, click Analyze disk. If you're prompted for an administrator password or confirmation, type the password or provide confirmation. Once Windows is finished analyzing the disk, you can check the percentage of fragmentation on the disk in the Last Run column. If the number is above 10%, you should defragment the disk. • Click Defragment disk. If you're prompted for an administrator password or confirmation, type the password or provide confirmation. Disk Defragmenter might take from several minutes to a few hours to finish, depending on the size and degree of fragmentation of your hard disk. You can still use your computer during the defragmentation process. Notes: • If the disk is already in exclusive use by another program or is formatted using a file system other t...
