Manually generating process snapshots

If you find Directory Opus is hanging or otherwise exhibiting unexplained behaviour, one important diagnostic tool is to generate a manual process snapshot (called a "dump") and send it to GP Software for analysis.

Note that in the event of an actual crash, Opus will usually save a crash log automatically. These can also be submitted to GP Software, following the instructions in the Automatic crash logs FAQ.

To generate a manual process snapshot:

  • Go to Task Manager (right-click on the taskbar, or press Ctrl+Shift+Escape)
  • Click on the the Details tab
  • Locate dopus.exe in the process list and right-click it
  • Select Create Dump File from the context menu


That will create a file in your temporary folder called dopus.DMP (or, if you do it again, dopus (2).DMP and so on).

To locate the snapshot file, in Opus or Explorer, type %TEMP% into the location field and push return. The actual path will look something like: C:\Users\<username>\AppData\Local\Temp\dopus.DMP.

The .DMP file will probably be quite large so you should compress it using 7Zip or Zip (from within Opus, right-click on it and choose Directory Opus Archives -> Add to Archive from the context menu).

Please email the compressed snapshot file to crashdumps@gpsoft.com.au. The file will contain personal data so you should never attach it to a public forum post.

If the file is too large for your email service, even after compression, you could upload it to OneDrive, DropBox or similar and email the link to us.

When emailing process snapshot files, be sure you include a link to the forum thread they relate to (or information on what happens, if there is no forum thread) so we know what we are looking for.
