I've been using Bitwarden for about 4 years now and cannot understand how a Password Manager does not export attachments when backing up your data. I understand this was the case when the only export format was a CSV file, but now with JSON files I can't get my head around the fact that I almost missed crucial SSH keys had I not checked the output. A simple solution would be to b64 encode each file and add it into an array!
It's even mentioned on their Help page - https://bitwarden.com/help/export-your-data/ but I still think it's a bit unacceptable that there isn't even a warning in the GUI about this.
And yes, I know there are ways to manually export the files, but I shouldn't have to do that.
The project is open-source, maybe send them a pull request?
