Windos said my HD 52 GB of free space, but my files are bigger!

Hello:

I use Windows 7-64 bit SP1.
In my c: drive properties it says I used GB 52.7 678 available (625 GB free)
However, if I select all the files in the root (c:\) including hidden and system, said properties dialog box I used GB 55.5, which is closer to 3 GB.
My question is if there is some sort of disc error, or there may be some unknown compressed files.

Note: Windows says I have MORE free space than I can actually count.

Thank you!

The disk properties is accurate.

Calculated by the Explorer file sizes can be inaccurate because of double counting of hard links combined with omission of records for which the current user has no access permissions. For example, Windows\System32 consists largely of hard links in Windows\WinSxS.

These articles, though ancient, explain which may explain the observed differences.

  • LUN showing sufficient free space but VMware showing low on space!

    Hello

    I have a very strange problem on a loan SAN, I don't have on hand the model number for the moment, but it's a PS6000 with NL - SAS drives.

    When I look in VMware to the DRLUN01 it seems that there is only 149 GB of free. When I look at the same SAN logical unit number, he says he has 985 GB free!

    The SAN is running the latest firmware and is connected to a server ESXi 4.1.0 through iSCSI. The LUN contains replicas of Veeam my production systems. When I talked to Veeam they notify that they have seen this twice but only know that Dell has solved the problems.

    As I'm not offered no support, even if I'm likely to spend August 20 k with Dell and have the Support Pro on my production SAN, I was wondering if someone can get ideas?

    Thank you

    If you have allocated (from the point of view ESX) all your space so it is a different matter.  ESX needs free space to work properly.  Temp files, the swapfiles, newspapers and snapshots of VMware.   For example, I usually create volumes of 600GO (in general), I leave at least 100 GB free.  If that gets close, I create a new data store and move the virtual machines or simply create the new on the new data store.

    Re: ESX knows.   Basics of basic/SCSI disk.  At the level of the storage disk, there is no "files" there are only blocks.   Each block has an address, called a LBA, logical block addressing.  Each volume (disk) reports so that its ability to the controller.

    The volume (disk) starts at LBA 0 and goes to the LBA The ESX server keeps a table of total blocks and when you make an entry, it selects and for use LBA.   LBA (and data) are written in the volume (disk).

    The table knows also how each volume is great, so he knows how many blocks there.   ESX server sends that data with the LBA ESX choose to use, at the same time, it will update the allocation table which is on this VMFS volume...  The table can then locate LBA (X) and write the data here.

    So, since you gave us (X) MB, we can infer that from the free space of the total volume.   Works fine as long as you never delete anything.   A removal of ESX is a WRITING on the VMFS allocation table.  We record this writing as others.   There is nothing to say the array, AMLA (X) is no longer used, so return to the Member's area.   This is where the new command comes in cancel the MAPPING.  Now the server can send a command that tells unallocate (free) LBA (X).   Use space will go down and free space on this member will go up.

    Re: Re-use of Array.   So since it's the ESX Server that determines the LBA to use, it will be re - write down as needed.

    Re: Free to the declaration space.  # Important indicator is what the operating system said, not the table.  Finally when SCSI UNMAP is indeed those two will be much closer together.   If a VMFS volume goes to 100%, you're in trouble.   ESX will no longer be a LBA list to choose from.  Entries will fail and VMs will go down.

    The table in use is assistance to make sure that you attach no more space than you did.

    That is if you had a table of 2 TB, you can create a volume thin MUCH bigger than available.  But up to what you actually write more than 2 TB, of a data value, you're fine.  If you do, then the table runs out of space and volumes to disconnect and all virtual machines would stop.  This gauge to judge when to buy more storage.

    If w/o UNMAP, finally the EQL GUI does NOT reflect the free space for a volume.

    Bottom line, follow what ESX (or any server) said being used and free space on a volume.

  • No free space after deleting files - trouble with optimized storage?

    Hi, I have macos Sierra and I deleted many files to my main drive and also to my external hard drive (both to the Mac OS Extended format) in preparation for the boot camp. I also emptied the Recycle Bin, although there is much less space on the two disks that it should be and the majority of the space is obviously indicated under "purgeable". I thought it would not be a problem, because I assumed that the space would be released, if I move all of the files there and if I need for the new Windows partition. However, this assumption was false. I can't simply use storage that I released. I can't move there all the files and I can't create the partition from free space. What can I do with it? It's pretty frustrating... Thanks for the help!

    You must use the Bootcamp Assistant to create the Bootcamp partition.

    Please provide details on the total space and free space on your internal drive. Post screenshots of what you see in system-> storage information. In addition, select the drive in Finder-I press control and post a screenshot of the window read the information.

  • Message says low disk space on recovery D, free space by deleting files to support...

    Original title: get the message on the recovery of free space low disk space by deleting files bear D. I deleted by using disk cleanup, but I still get the same message?

    I got disk spave low recovery D ask me to use Disk Cleanup to delete the old files. I deleted many files and none using programs and I still get the same message. How can I clear this problem? I'm using Vista Home premium.

    Hello

    In NO case should remove anything from the recovery partition.

    Your recovery Partition was photographed on your hard drive during the production of your computer by the manufacturer for all of these reasons.

    1. to reinstall Vista from in the case of a failure of the system, based on individuals or the keys at startup.

    F10 or Alt + F10 or F11 are a couple of different manufacturers use sequences.

    You will need to ask your manufacturer for proper sequence.

    2. to make the recovery disks on if your drive hard breaks down, so that you can then reinstall the operating system on a new hard drive.

    Also ask them how to make records.

    Your D: Recovery Drive is should not be used for backups, defragmented, etc..

    There are backups on an external hard drive.

    To resolve the problems that have arisen with the recovery D: Partition, you will need to contact the manufacturer of your computer to remove all that has been added to it.

    See you soon.

  • you have to have free space, or your files will automatically separate?

    I have about an 80 gigabyte and I want to share it at halfway but its full, so I was wondering if windows will automatically share files

    Your question is not particularly clear.

    Windows will only save a file on a single path then if the Act of writing a large file will fill a particular drive that the write will fail completely with a lack of space error.

    When writing multiple files to a removable device, it can request a change to the device when it is full.

    It is not generally recommended to fill out a capacity HARD drive as standard household tasks will not work. You should always have at least 15% of free space on a disk partition.

  • only 1.9 GB of free space for linux file

    I just installed red hat linux enterprise 5.1 on fusion 2.03 using easy install.  It's on a mac pro using 10.5.5.

    When I create a new folder on the desktop or in the folder, it says only "1.9 GB of free space" is available.  In the settings, the virtual disk is 40 GB.

    Why can't I get more space?

    Probably not a problem merging themselves, and you should fix it as you would if you had a physical disc.

    I would check the configuration of logical volume and/or partitioning (virtual) startup disk that was made at the facility, RHEL 5. I do not know what to install Easy out of the box. Just as a physical disk, if she does not have in place the disc to your expectations, it may not be clear, that you suspect in allocated to file systems. If your startup disk has been implemented to use LVM and space not assigned to a disk volume, you may be able to expand volume/file system containing your home directory.

    Better yet, do not use Easy Install. If you are competent enough to install Red Hat Enterprise Linux, you don't need the training wheels of Easy Install

  • Time Machine - I have masses of free space, but Time Machine keeps deleting old files - why?

    Time Machine - I have masses of space free (about 2.5 TB) but time machine keeps deleting files of more than nine months. Is there a parameter limiting that I don't know?  My backup drive is a 4 start Drobo drive.  I have everything works fine except this irritating issue.  Any ideas out there?

    Hello Mike Oscar.

    I hope that I am able to help you with your concern today. If I understand you correctly, in Time Machine, files of more than 9 months are deleted. Time Machine to save space. I'm not sure if Apple is allowing us to extend this period to 12 months or even 16 months, but it would be a great recommendation. I hope I could help you with your concern.

    Hello gregor gregor gregor.

    Thank you for using communities of Apple Support. It's my understanding you are needing help with upgrading to Sierra, as the Mac App Store gives more the possibility to download. I want to assure you that you can upgrade and enjoy Sierra successfully.

    If you quit the Installer do not click on continue, you can open it later in your Applications, Launchpad or Spotlight folder. Looking for a file named Install macOS Sierra. During the installation, your Mac may restart several times. It performs then a few initial configuration in the background tasks. Although these tasks are ongoing activities such as the use of Spotlight or Mail may not seem as fast as they were before.

    Anyone who has had this and what I can do about it?

    Since your not sure what the 'others' are I would recommend you to restore your iPhone. I know that you will lose all your data, but not restore from a backup of iCloud so start as a new phone. You can back up your choice and if necessary to write all your contacts on a sheet of paper and then add hide them. Depending on the severity, you want that storage

  • Satellite A215-S7422: free space on the HARD disk decreases every day

    Hello everyone,

    Hi I'm alex.

    I've owned a computer laptop "SATELLITE A215-S7422.
    I got 147 GB of my hard disk drive memory, I got 119 free space but as I noticed it is constantly down even if I do not download anything.

    When I saw this first I try to get it back to the factory setting and I had 128 GB of free space, and every day it is significantly down.

    Everything I do is look at you tube.

    Can someone explain to me what is happening and what I can do about it...

    It would be much appreciated.

    Thank you

    Hello

    There is a simple explanation why HARD disk space decreases each time while watching Youtube videos
    The video stream is always stored on the HARD drive in the internet files folder and in time.

    So from time to time, it would be desirable to remove these files and to clean the folder of files over time.
    I use the CCLeaner. It is free software and can be downloaded from different pages. Google simply
    This program is very useful. It cleans the HARD drive and removes the garbage all registry.

    You should test.

  • Why defragment reduced my free space on the disk?

    I show to have only 10% of free disk space on... VISTA lecteurC.  Thought that defragmentation would increase free space, but it reduces.  Don't understand why I should only less than 10% free space - I do ot DOWNLOAD music or movies and have very few pictures, and yes I'm dim when it comes to HER.

    I suggest that you use CCleaner to remove your temporary files because it is more aggressive than WIndows disk cleanup. With a C: drive however, this size you always are going to have problems. Size fluctuations are most likely due to points of system restore and Volume Shadow Copy.

    You can reduce the space they are taking by using disk cleanup and choose the option "files for all users on this computer." When you get to the window to select files to delete, click on the 'More Options' tab and click on the button 'Clean up' in the section 'Sytem Restore and cliché '.

    This will make that space available for a time until several restore points are created.

  • Upgrade Windows XP to Windows 7 has no enough free space on hard drive

    Hey, I'm trying to move from XP to 7 (custom installation), and after a while, you have to choose where you want to install windows 7, so I chose the disk which has more than 100 GB of free space, but the thing tells me that its not enough free space... Please help.

    Greetings

    Albert

    Did you start the Windows XP installation?

    You have external storage devices connected to the machine? If so, disconnect them all. In addition, if you have several internal storage devices, disconnect them all except the target device where Windows will be installed.

    Boot from the Windows 7 DVD
    Click Install now
    Accept the license agreement
    When the option is displayed to select a type of installation, click (Custom advanced)

    Select the disk partition where you want to install Windows 7 click Next.

    You will receive the following warning:

    The partition you have selected may contain files from a previous Installation of Windows. If so, these files and folders will be moved to a folder named Windows.old. You will be able to access the information in Windows.old, but you will be able to use your previous version of Windows.

    (At all costs, do NOT click on anything in Format, deletion or Partition name.) So even do a custom installation, your personal files are still kept. Click OK

    The installation program will now begin installation. During installation, your computer will be restarted several times.

    Once the installation is complete, you can complete the Out of Box experience as the choice of your laptop, create a username, password, your time zone. You can then proceed to download the latest updates for Windows and reinstall your applications and drivers.

    You can then retrieve your personal files from the Windows.old folder and reinstall all of your applications and drivers.
