Using Docker - Files can't be identified: No content found in NCA containers.

2026-01-01 19:37:21.927] INFO (library) Identifying file (9/201): Contra Anniversary Collection [0100DCA00DA7E000][v0][Base].nsp [2026-01-01 19:37:21.929] WARNING (library) Error identifying file Contra Anniversary Collection [0100DCA00DA7E000][v0][Base].nsp: No content found in NCA containers.

I've used hactool to confirm that there is content in the NCA containers. What do I need to do to get these (and other files that have the same issue) recognized? A lot of my files are recognized.

Me too.

No content found in NCA containers

Any solution for this?

Thanks!

Hi, it's very hard for me to troubleshoot this issue given the very generic error message, and me not having access to the problematic files. I've pushed a fix to eliminate this generic message and always propagate the actual error message, in the logs and in the database. You can try it with the develop image.

After running the new version you should see more explicit error messages in the logs. If you want to inspect the database for all identification errors use the command:
sqlite3 config/ownfoil.db "select filename, identification_error from files where identified = 0;"

Then for each problematic file confirm that it can be opened with NxFileViewer and that there are no errors, and let me know why Ownfoil has trouble reading it.

Also, are you experiencing crashes due to memory when the file cannot be identified?
