Desktop Client best way to find and open document by ID

You can search by object type and object ID via the advanced search: https://www.m-files.com/user-guide/latest/eng/status_based_conditions.html#filter_settings_status

Furthermore, my experience is that simply entering the ID into the Quick Search bar will also usually return the correct document. There may be several search results but it should be quite quick to identify the correct one from those if you don't want to use the advanced search option.

Agree with Joonas but would like to add that using IDs can be tricky if you have used Replication to move documents or other objects between vaults. This would lead to a situation where Display ID is not same as the Internal ID. That's when users get confused and search results do not always come out as expected.

I see, it was not at all apparent that the "Additional Conditions" rectangle was a button leading to a dialog instead of simply referring to the list of properties below it. This would explain why the fields I knew existed would never appear in those drop-downs!
