Delete all auto-backups on Windows doesn't do what the name suggests.

It clears the entire directory designated for auto backups! 

In my case it cleared the entire backup directory where I keep all sorts of backups from my Windows machine - not what I expected it to do at all.

This is not mentioned in the Knowledge Base article on backup.

Is this a bug or a design feature?

(Luckily I noticed what it had done - and equally luckily its not a secure erase so I was able to get the files back from the Recycle Bin - but this could have been much worse. I've now created a separate subdirectory for mSecure Backups and will probably never use that feature again anyway.)
