Elements Organiser Catalog Backup - Very stange behaviour

[SimonW]

Folks,

In my Elements V9 Organiser I regularly use File>Backup catalog to external hard disk. I've never yet had to restore from a backup (touch wood!). But today out of curiosity I opened the backup folder on the external disk. In addition to copies of the photos (with file names changed) and some other files I didn't look closely into, were very many pdf files. I opened one of these and was very surprised by the result so I tried several others. (I have Elements 9 on a desktop and a laptop, both with Windows 7 - they both do the same thing.)

In short it appears that the Elements Organiser has backed up every pdf file on my system (hopefully in addition to all the relevent photo organiser files). Nowhere in the Organiser, or in the help system, is there anything to suggest it also catalogs and/or backs up pdf files, and I can find no way of preventing it from doing so.

Has anyone else noticed this?

I have a large number of work-related pdf files on my system which I would not want made public, and as I believe some versions of Elements can sync with "the cloud" this might be a security problem.
