Well, this /did/ work as the code intended, but not as a user would
expect.
As of commit e549808c0e90, the resource directories would list _all_
attachments referencing some record, by default. This meant that a
newly created folder with files [and subfolders with files..] would
have all the files listed at the root folder, too
eg. /Dirs/Products/Product-A/ + [ /dir2/a.txt, /dir2/b.txt ]
would list a.txt, b.txt under ../Product-A/ , too.

Now, the algorithm is improved to handle such a case and turn off the
"find all" flag[1] so that child files will be contained in their
folders[2].

[1] I'm now glad I had left that option there.
[2] still, files may all appear at the root folder, too, if this has
the "find-all" flag set.
