Where are the email attachments stored?

Hello fellas, happy new year to all! I've a burning question - where are email documents saved?
I know the email attachments (word, excel, ppt) can be accessed and DELETED from the Office app. But PDF Reader does not have the delete function. The PDF file remains even though the email (from which it was downloaded) has been deleted and trashed. That set me thinking... Would WP therefore retain a fair bit of unwanted stuffs overtime? WP does not come with native (or 3rd party) file explorers, so I find it hard to understand what's going on inside my phone directories.

Thank You for bringing this question dude.... Even I posted a thread asking for File Explorers like those in Android and Symbian but of no help. !!
