When receiving an email attachment and i retrieve that from lets say the BES server... where does the file get downloaded to for viewing? Can that temporary location be pointed to the SD card?

When or how does that file get purged/deleted?

Since the blackberry doesn't prompt me where to save the file (at least when it's a known file type , like lets say .doc) it just opens it. I know that it's somewhere on the because it doesn't have to re-download it when i wish to view it again.

Thanks in advance.
