I want to know if there's a way to send .cdp files by E-Mail. The reason why is that I can let other owners of Trainz try out the routes I've been working on and then determine if I will upload them to the Download Station.
You may want to zip them first, zips have a crc check digit so you know if the entire file has arrived, .cdp files do not. Currently Google drive seems to be a common method for sending big files or you can use skype file transfer.
Hmm, you could use 7zip found at www.7zip.org (open source), but as Shane suggested,
Windows XP and higher (don't know about 8) has zip compression buildin in the OS.
Have you and the one you want to send it to (get)on Teamspeak 3 and send it thru the file brower.
Have your CDP on your desk top then drag and drop into file brower.
Have your friend down load from there to his desk top then open content manager and drag and drop into CM.
