So you’re happily working along, when all of a sudden BAM! Revit crashes. Hopefully, you’ll be given the opportunity to create a recovery file. So, what do you do with that file?
In a small number of cases, Revit isn’t able to save a real recovery file. So, take a look at the size of the file in Windows Explorer. If it is absurdly small, like 12k, then you are out of luck. If the size is similar to the original file, then you’re probably good.
The next step is to start Revit by double-clicking on the icon (not the file). Then, using the Open command, browse to your recovery file and highlight it (not double-click). Click on the Audit option at the bottom of the dialog, click OK on the notice that appears, and click on the Open button.
Once your file has opened, take a few minutes to check to see that everything appears normal. Once you are satisfied (or as much as you can be), click on the Syncronize button to sync your model. Be sure to relinquish everything. Exit Revit.
At this point, regardless of whether or not the recovery file worked for you, delete the original local file, the recovery file, and the associated backup folders for the local file and recovery file. Get a new local file and continue working like normal.
And don’t forget – Save locally often, just in case.
