Hi. I opened your file in Dorico Pro 5 (after removing the .zip) and resaved it. There were no problems opening it.

hi Steven
the problem is this is the very beginning of my work on this track. The actual track is 64 measures with 7 staves.

Are you able to upload the file which won’t open?
Also, have you checked in the Dorico backups folder. As I’m on Mac, I don’t know where on Windows this folder would be, but on the Mac it is in the Users folder > Documents > Dorico Projects > Backup Projects. If you can locate the corresponding folder in your Windows setup, it should have a few recent backups. See if any of those will open.

I have numerous files I’ve made trying to get around this problem the one I’m attaching is the autosave file that was created at the time of the crash. I believe this should contain the info but that the software was damaged so dorico rejects it as an error

Mario-[AutoSave] (2).dorico (276 Bytes)

I can tell by the file size (276 bytes) that there will not be anything usable in that file. Dorico projects are usually at least a few hundred kilobytes, ranging up to megabytes for larger projects. Can you find any other possibles for that project by searching for file names ending in “.dorico”?

From the Dorico manual:

in the documents/steinberg/ I have crash dumps only (I have attached one above)
Dorico backup file I modified to only 1 backup not 5 and that one does not show the complete score
Dorico autosave I have 3 but while they show 700+ KB the file reproduced is minimal and not the complete document I was working on
my understanding was that you had a internal recovery tool that could retrieve the missing data

Dorico 5 AudioEngine 5.6.42 64bit 2026.6.3 16.25.02.484-freezedump.dmp (729 KB)

he attached file has 593KB and the score.dtn has 725 KB uncompressed

(Attachment score.dtn is missing)

This probably won’t help in the current situation, but I make sure that when I create a new Dorico project I enable the checkbox at the bottom of the Project Info window (shift-I) to “Generate preview thumbnails when saving”. That creates a PDF of the layout that is showing in the main window when the file is saved - I try to remember to show the Full Score layout when saving. The PDF is saved inside the Dorico project and can be viewed by changing the file extension from .dorico to .zip and opening the file using a file decompression utility (such as UnZip, although not all such apps succeed if the project has become badly corrupted). When decompressed, the file turns into a folder, which contains a folder called “preview” (might be a few levels deep). Inside that will be the PDF, also called “preview”. This procedure is best done on a copy of the file, just to be safe. Depending on how far Dorico gets through the saving process before the corruption/crash/etc. occurs, the PDF might or might not get created. If it is there, it will at least show you what was in the project and will assist in re-inputting the contents either manually or scanning it and saving to musicxml or MIDI. Not a perfect solution, but better than nothing at all.

Yes I already went through that process and the corruption doesn’t allow me to see the preview which is why I contacted Dorico support I thought they have a tool that can that can at least provide a visual of the score. I can open the score.dtn into notepad and see the computer data for the score but its impossible to read
