10.2.2 Attachment options

‘org-attach-id-to-path-function-list’
     When ‘ID’ is used for attachments, the ID is parsed into a part of
     a directory-path.  See ‘org-attach-id-uuid-folder-format’ for the
     default function.  Define a new one and add it as first element in
     ‘org-attach-id-to-path-function-list’ if you want the folder
     structure in any other way.  All functions in this list will be
     tried when resolving existing ID's into paths, to maintain backward
     compatibility with existing folders in your system.

For IDs, we use `org-attach-id-uuid-folder-format' by default - it puts
attachments under

<org-attach-id-dir>/<first two letters of ID>/<the rest of ID>/attached-file
