If you do not want to receive this error message, and do not want to use the Disk Cleanup tool to free disk space:

  1. Start the Registry Editor
  2. Select HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control \ FileSystem
  3. Select Edit > New > DWORD Value and name it DisableLowDiskSpaceBroadcast
  4. Set the data value of the DisableLowDiskSpaceBroadcast value to the appropriate value from the following table:

    A 1
    B 2
    C 4
    D 8
    E 16
    F 32
    G 64
    H 128
    I 256
    J 512
    K 1024
    L 2048
    M 4096
    N 8192
    O 16384
    P 32768
    Q 65536
    R 131072
    S 262144

    If you want to disable the error message for more than one drive, you can add the data values of the drives located in the TABLE, and then set the data value of the DisableLowDiskSpaceBroadcast value using the sum of the data values that you added. For example, drive E has a value of 16 and drive G has a value of 64. These two data values added together equal 80. To disable the low disk space notification for drive E and drive G, set the data value of the DisableLowDiskSpaceBroadcast value to 80.
