I have gone through the documentation and code for sample app, and figured out that files/objectbox/objectbox/data.mdb is the default file where all data is stored.

Assuming my understanding is correct, I have a couple of questions that I couldn't find documentation on:

  1. I want to have a backup/restore functionality in my Android app. Assuming I use native SQLite DB, I know I can upload the .sqlite file to cloud, and then download it on the same (or even a different) device to restore it. Can the same be done with data.mdb file?
  2. How about lock.mdb? Do I need to copy\upload it along with data.mdb?

  1. Ensure that the file is not opened (e.g. by any BoxStore) to enforce a consistent state of the data.mdb file for backup.

  2. The lock.mdb file is not relevant for backups

Thanks for the response. I played around it with it while waiting for the response (which by he way pretty quick, thanks), and figured it out. Best.
What is lock.mdf file? What is it's purpose? Why is it generated other than data.mdb file?
The lock.mdb file keeps track of internal stuff, e.g. coordinating "reader" resources. It does not contain application data.
how to open/read this .mdb file of objectbox?
ObjectBox databases can be viewed via the Admin web app: docs.objectbox.io/data-browser
