exe (executable) files are probably the highest on the list of files that can carry viruses or otherwise do malicious damage to the machines they land in during their travels.
exe files generally run by doubleclicking them, without the need for supporting software. Years ago, people with malicious tendencies would have viral exe files attached to emails which baited/misled the recipient into opening the file (running it by simply clicking it)
Thank you very much Ned, for the information. Would you happen to know what to do to the Projector file in order to send it safely through e-mail?
I imagine there are many Flash users using this mode of graphics communication, that by the way, its the only file that protects your work from third party acquisition that I know of.
Thank you Ned.
