System Volume Information ?
When defragging HD using Piriform's Defraggler, there is always a file
that's spread over a number of blocks and can't be consolidated. Defraggler show a bit over 3500 blocks, each having a bit over 1/4 GB. Path to the fragmented file is listed as "C:\System Volume Information\", and the file accounts for over 5% of the HD. Any "pearls of wisdom" relating to this, most welcome. |

Any "pearls of wisdom" relating to this, most welcome. Administrator command prompt http://www.thewindowsclub.com/defrag...s-in-windows-7 http://www.thewindowsclub.com/disk-defragmenter-windows # -w Perform FULL defragmentation of files of ALL sizes. defrag C: -w But note that the defrag command was a work in progress, and my experience is, any useful option doesn't work. (You may see a web article like the one above, where the feature is now defunct.) Or, the option was removed. And so on. The track record on it isn't that good. The SVI folder is "Access Denied". Have you noticed ? The defragmenter doesn't care, but then again, there's a magic reason the defragmenter should not be in there. There are shadow copies in there, which are not regular files (you can break the files simply by reading them), and it's not certain what the outcome would be of defragmenting the representation in one of those. Going to System control panel, System Protection (i.e. System Restore control stuff), you have the option of deleting restore points, or setting the restore point max size to zero, which can erase most of the contents in there. I don't know what happens if you do that while your backup software is tracking Incrementals with a persistent shadow. It's possible in Windows 10, that if File History is enabled, it could be using shadows for tracking file deltas (before transferring the information to an external USB hard drive). You have plenty of options, many places for Whack-A-Mole action, but in the greater scheme of things, you should just leave well enough alone. The commercial defragmenter you're using, has put your user files in nice, neat order for quick loading. Same as executable EXE or DLL files in the system folder. And really, you should be satisfied with that. Defragment what it allows you to defragment... then move on. I usually keep SVI in "almost switched off" state, so this isn't usually a problem. For example, I might set the max size to 3GB, instead of whatever the system set it to. On some OSes here, it's turned off completely. A Macrium full backup might create a VSS shadow, but the shadow in my case is not likely to be persistent, so no harm done. Paul |

Thanks Paul. So very much good info as usual.
Going to System control panel, System Protection (i.e. System Restore control stuff), you have the option of deleting restore points, or setting the restore point max size to zero, which can erase most of the contents in there. I don't know what happens if you do that while your backup software is tracking Incrementals with a persistent shadow.

And really, you should be satisfied with that. Defragment what it allows you to defragment... then move on. Even when I delete all restore points, the file persists. Just going to leave it and accept the apparent 5% fragmentation. Thanks again ... Steve |
