  • Error: "DMError" when optimising

This information applies to MYOB AccountRight version 19. For later versions, see our help centre.




The following errors may occur when optimising your company file:

"DMError [-225:5116:0:0]. An error has occurred while trying to compact the file."

"DMError [-230:5116:0:0]. An error has occurred while trying to compact the file."

Errors like this mean either:

  • There are too many lock files for the process to be completed. For instructions on how to find and delete these files, see Error: "No more than 10 data files..." when opening a company file.
  • The file is being optimised over a network. Make sure you optimise the company file on the same computer where the company file is stored. To check the location of the company file, go to the Accounts command centre and click Company Data Auditor. The Company File Overview window will be displayed which includes the location of your company file.

If the error persists

If you're using AccountRight in a network:

  • Make sure the company file is optimised on the computer where the company file is stored. This is faster and more reliable than over a network.
  • Restart the computer and try optimising again.
  • Copy the company file to another folder, for example to a new folder on your desktop, then try optimising again. If the optimisation is successful, re-name your original (un-optimised) company file, then move the optimised company file back to its original location.
  • The company file may be corrupted in which case you can restore your latest backup. For more information see the AccountRight help (Australia | New Zealand).
  • Our Data File Repair Team can fix corrupt company files. See our website for more information on this service (Australia | New Zealand)
