It sounds like it.
And my vbulletin import script, which does handle non-linked attachments, doesn’t look for them in that table, so you’ll need some custom code to deal with that, even after I get around to submitting a PR with my script.
EDIT: and it also means that I think that even if they were linked in-post they still wouldn’t work, since they aren’t where the script expects them in the database.
Good news! I don’t know exactly how the import script handles it but it does! After making the files accessible to the import container and digging a bit in the script I found that it works. The only problem I had was that the file name which I tested it on contained an ä and thus some weird encoding shit prevented the script from finding the file actually. After fixing the filename the import worked and the attachment appeared at the post!
Thanks a lot for all the tips! 
Awesome! Glad the magic worked for you! (Oh! I and I see now that I was looking at the vBulletin script and not bbPress, hence my confusion. That explains why I couldn’t find the table!)

Any idea please ?
Thank you 
Thanks for this tutorial, @vinothkannans!
I’m stuck modifying bbpress.rb
After running sudo nano script/import_scripts/bbpress.rb it opens the file editor, but when I tray and save, it says there’s no such file or directory:
It’s a totally fresh install.
Many thanks,
Jake
In the above guide, I used /var/discourse directory to install the Discourse development environment. If you installed it in a different location then make sure to cd to that directory (‘~/discourse’ in most cases) instead of the above before running the sudo nano script/import_scripts/bbpress.rb command.
Hi,
I don’t see “script” path in /var/discourse folder.
This is what /var/discourse/scripts/ looks like:
That’s right.
You’ll need to set up a development environment or follow instructions in other import topics about how you might run the import script inside of a production container.
Finally found How to use the bbpress import script - or any other import script with mysql dependency - developers - Discourse Meta for missing part.
Thanks
@vinothkannans I’m trying to migrate from WPForo to Discourse and the script/code is beyond my capability. Would you (or anyone else) be able to help me with this? Thanks.
You might have better luck posting in marketplace. There are a number of people who monitor that category who can help.
Though we also have the migration category too for specific migration questions. 
I’m getting the following error when I follow the guide and get to the point where I run the import script. I installed discourse as per these instructions
myuser@tmp-discourse:~/discourse$ IMPORT=1 bundle && IMPORT=1 bundle exec ruby script/import_scripts/bbpress.rb
[!] There was an error parsing `Gemfile`: You cannot specify the same gem twice with different version requirements.
You specified: sqlite3 (~> 1.3, >= 1.3.13) and sqlite3 (>= 0). Bundler cannot continue.

I got it workingby changing this in the Gemfile

I also needed to install this package in my Ubuntu 22.04 LTS install
sudo apt install freetds-dev
