In reality its Windows telling you its out of memory (not so much so ‘physical’ memory but rather ‘virtual’ memory). Windows uses physical memory for running applications and virtual memory (or also referred to as a ‘page file’) for background operations.


When you work extensively with trips (combining and splitting especially), Little LogBook works live with changes to a database and said entries actually consist of hundred and thousands of datapoints and references. Windows by default allocates a minimum amount of space to virtual memory but more often than not, when you go and change it, you will note that the value recommended is sometimes 3 times the value Windows has allocated.

You could simply work till your Windows runs out of this memory and close Little LogBook and carry on again, but to increase this value and allow more memory for Little LogBook and other software applications, you could follow these steps: 

  • Click on Start and then RIGHT click “Computer” and click on “Properties” (in Windows 8, click the Start Screen and type the word "Computer". RIGHT click that and click the Properties option at the bottom of the window)
  • Click on the Advanced System Settings option in the navigation pane on the left:
    • 1. Click on the Advanced tab at the top
    • 2. Click the Settings button in the section “Performance”
    • 3. Click the Advanced tab again at the top in the window
    • 4. Then click on the Change button under “Virtual Memory”
    • ? Look at the values at the bottom (I boxed it in blue in the screenshot below). Usually the allocated amount is lower than the required amount. Take note of this as you will use the required amount and set this as your minimum amount just above it
    • 5. Off tick the option at the top of the box stating “Let windows manage.....” (not shown here because I took the screenshot from Windows XP) and click on Custom size option. Make the minimum (or initial size) the same value as the required amount shown at the bottom of the box
    • 6. Set the Maximum size to be at least 1.5 x that of the initial size, eg if initial size is 1000, make the maximum size 1500.
    • 7. Click on Set to set it and then on Ok. It will probably prompt you that a restart is required.


  • Take a look at the screenshot of the above steps, numbered accordingly:




Keep clicking OK until all the boxes are closed and it asks you to restart. Restart the PC for the change to take effect. Don't worry - you cannot break anything by doing this and in fact will just improve your PC’s performance as a whole.
