Hi,

I have a windows server 2016 standard edition. It has a 1.8TB drive in it which acts as the network share. There are approx 400Gb of files on this drive. The server is reporting that there is only 66Gb of space left on the drive. I have error checked the drive and no errors reported.

Any ideas?

    Hello,

    You can try to run the following cmd command with administrator rights to clear the shadow copies in the system volume information folder under the specified drive letter.

    delete shadows volume E:

    So I did as suggested and found that the system volume information is huge. I am guessing these are system restore points? How do I remove them? I tried going to control panel but I get an error sysem restore could not be started. Also the tab is missing under system > advanced settings Thank you

    Hello

    Thank you for posting in Microsoft Community forum.

    There is insufficient remaining space on the drive, which may be related to the following points:

    1. Hidden or System Files: There might be hidden or system files that are taking up space. You can check for these files using the built-in Disk Cleanup tool. Press Windows + R keys to open Run, type cleanmgr and press Enter. C: drive is selected by default, simply click OK to continue. Click the checkboxes in front of the files that you want to remove and click OK. Confirm the deletion in the next window.
    2. NTFS Permissions: File attributes or NTFS permissions might prevent Windows Explorer or a command prompt from displaying or accessing files or folders. You might need to adjust these permissions to see and manage these files.
    3. Cluster Size: The NTFS volume’s cluster size might be too large for the average-sized files that are stored there. You can check the current cluster size and volume statistics by running a read-only chkdsk command from a command prompt.
    4. Virtual Memory: If your server is using a lot of virtual memory (paging file), it could be taking up space on your drive. You can manage this by pressing Windows + R to open Run, type sysdm.cpl,3 and press Enter. Click Settings under Performance on top of System Properties window. In the Performance Options window, switch to Advanced tab and click Change below Virtual Memory. Uncheck Automatically manage paging file, then click C: drive > No paging file > Set.
    5. Volume Shadow Copies: Windows Server 2016 uses Shadow Copies for backup and versioning, which can take up a significant amount of space. You can check and manage these copies from the Shadow Copies tab in the properties of the drive.

    Best Regards,

    Thank you for your reply. The problem is not with the C drive it is with a seperate drive that is used as the network share. I am not using shadow copies and I have checked for hidden files. The drive has been working fine for 5 years and it is only recently exhibiting the problem

    You can also download two tools PSTools.zip and TreeSizeFreeSetup.exe from the following link, copy them to the machine in question and decompress them. This tool can check the space occupied by each folder on the disk.

    The download link is as follows:

    www.jam-software.com

    PsTools - Sysinternals | Microsoft Learn

    After the installation is complete, run CMD as administrator and run the following command:

    cd pstools path

    psexec -s -i "treesize path"

    The purpose is to open the Treesize tool with system permissions and view the disk space usage.

    In the treesize console, click select Directory and select the disk you want to view:

    size is the current disk space occupied by the corresponding file. We can try clicking the "+" next to the folder on the far left to view files that take up larger space:
