Attachment Storage Scheme

[Brad L]

How exactly are attachments stored in the filesystem? Does each member have their own directory like vbulletin, or are there shared directories? I have a xenforo forum under development, and the few existing members' attachments are all located here:
/data/attachments/0/
/internal_data/attachments/0/

I realized earlier today that my file permissions for the data and internal_data directories were incorrect, so I'm not sure if this is intended behavior or an effect related to the incorrect permissions.

There is one main directory, with sub-directories containing 1000 files.

The /data/attachments directory is for the thumbnails.
The /internal_data/attachments directory is for the original images. This directory is php protected which enables the contents to be restricted to certain groups/users using the permission: View attachments to posts.

Don't they technically contain 999 files, because the 1000th file would carry over to the next sub-directory

Thanks for the quick replies. Are you two saying that the folder names (/internal_data/attachments/0/) have nothing to do with a member's userid?

 

[James]

The 0 is the group they belong to. The first 999 attachments will have /0/, then 1000-1999 will have /1/, then 2000-2999 will have /2/, etc.

Correct.

The only time the user id is used is for avatars.
Your user id is 616 and therefore your avatar is: http://xenforo.com/community/data/avatars/l/0/616.jpg

When a post is permanently deleted, any attachments within get removed from the server too right?
I thought this was the case as to not leave orphan files everywhere?

 

[Paul B]

That's correct.

They're deleted the next time a cron cleanup task runs.
