Windows 10: Low Disc Space Warning Solved

    Low Disc Space Warning

    I've got this nagging warning "LOW DISK SPACE" on drive G (didn't know I had a drive G). It cannot be remedied. It shows the disc as empty when I check on explorer. What can I do?

    Right-click the Start button, on the resulting list click Disk Management, should show all the drives and the partitions on the drives. There will be a partition or a few that you shouldn't have direct access to with a standard installation of Win10, may be marked as System Reserved, System Restore, etc. and will be relatively small. The partition involved may have inadvertently been assigned the letter G:. Or it may be an SDHC memory card plugged in or a USB Thumb drive. Or could it be you have a second internal drive?

    It's shown as an 'OEM partition'. Disk Management doesn't allow you to manage some types of partitions. You should be able to remove the drive letter using Diskpart from a Command prompt (Admin) though. MiniTools Partition Wizard should be able to remove it too. For Diskpart, first SELECT the disk containing the partition, then select the partition concerned. You should then be able to use the REMOVE command.
        Removes a drive letter or mounted folder pathname from the volume
        with focus.
        LETTER=<D>  The drive letter to be removed.
                    The mounted folder path to be removed.
        ALL         Removes all current drive letters and mounted folder paths.
        DISMOUNT    This parameter may be used if 1) all drive letters and
                    mounted folder paths have been removed from the volume, or
                    2) the ALL parameter is specified.  This parameter
                    specifies that the file system is to be dismounted and
                    the volume taken offline. If other processes are using
                    the volume, DiskPart closes any open handles before
                    dismounting the file system and taking the volume offline.
                    You can bring the volume online by assigning it a driver
                    letter, by creating a mounted folder path to the volume, or
                    by using the ONLINE command. DISMOUNT will fail if used
                    on a volume that has any remaining drive letters or mounted
                    folder paths. For scripting, using REMOVE ALL DISMOUNT is
        NOERR       For scripting only. When an error is encountered, DiskPart
                    continues to process commands as if the error did not occur.
                    Without the NOERR parameter, an error causes DiskPart to exit
                    with an error code.
        If no drive letter or mounted folder path is specified, DiskPart removes
        the first drive letter or mounted folder path it encounters. If the ALL
        parameter is used, all current drive letters and mounted folder paths
        are removed. If the DISMOUNT parameter is used, DiskPart closes all open
        handles to the volume and then dismounts the volume and takes it offline.
        The REMOVE command can be used to change the drive letter associated with a
        removable drive. You cannot remove the drive letters on boot or
        paging volumes.
        A volume must be selected for this operation to succeed.

    You can select the volume direct - no need to select disk and partition separately...

    • diskpart
    • select volume G
    • remove
    • exit

    It looks like this (although I removed D not G here)
