I want to backup my pictures. Where are the original pictures stored in the filesystem ?
It doesn't matter. That information is stored in the database.But they are not organized in categories/albums like on the XF
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.
You can't do a partial restore of a site anyway so it doesn't matter.But they are not organized in categories/albums like on the XF
