fukino@: Could you take a look at (or triage) this issue?

yamaguchi@, please correct me if I'm wrong about the current implementation.

After we add Text app as a default application, I assume this is an expected behavior.
I guess followings happen:
1) Text app can open *.ica file, since its mime type can be sniffed as text.
2) Citrix Receiver is installed, but haven't been opened from Files app.
3) In this situation, Text app is treated as a default app for the file, since default built-in app is prioritized over unused third-party apps.

If Citrix Receiver is chosen from OPEN dropdown menu in Files app, it will be respected after that.

That said, I think matching of file extension should be prioritized than matching of mime type.
In this case, Text app matches the ica file by mime type (text/plain) and Citrix Receiver matches the ica file by file extension.
Unless the user explicitly choose the default app, Citrix Receiver should be prioritized.
+weifangsun@ to confirm the expected behavior.

I think it will not, but only after user explicitly chooses the app by "change default" menu, with the existing logic.

https://cs.chromium.org/chromium/src/chrome/browser/chromeos/file_manager/file_tasks.cc?q=file:file_tasks.cc&sq=package:chromium&dr&l=629
It gives higher priority to the built-in apps than other non-generic handlers.

OK. Then this is the expected behavior at this moment.

Let's consider respecting file extension more than mime type in M66.

Thank you!

This bug is still in my queue as part of MIME (and file extension) related work, next steps haven't been identified yet.

Thanks for the update. Is there any sort of estimate on when this may be addressed?

Still working out priorities for fixing. This is related to the more general MIME handling bug https://bugs.chromium.org/p/chromium/issues/detail?id=848124 Will update when I have a better idea of an estimate.
