Dominik, I've added a bit to the Security section of the Help. I thought about adding it to the additional FAQ, but security seems correct to me.

Features Time Fields and Entry Attachments
KeePass supports time fields: creation time, last modification time, last access time and expiration time. You can attach files to password entries (useful to store PGP signature files in KeePass for example).

The built-in editor/viewer stores the data being viewed in memory.
Files the built-in editor/viewer cannot handle (e.g. PDF files), will be extracted to a (EFS-encrypted) temporary file and opened using the default application for this file type. After finishing viewing/editing, the user can choose between importing or discarding any changes made to the temporary file. In any case, KeePass afterwards securely deletes the temporary file (including overwriting it).
I should have previewed that before hitting the post button. :)
cheers, Paul
Good idea; I've added it.
Thanks and best regards,
Dominik
