FileChute makes sending files easy. Just drag a file and drop it on FileChute. FileChute puts the file on your .Mac account and generates a web link for retrieving the file all in one step. Next drag the generated link into your email and you're set to go. And since what you're sending is just a link, your recipients can retrieve the file from a Mac, a PC or any other platform.
You can even drop multiple files or folders at once. FileChute automatically creates an archive in the format of your choice - it supports dmg, zip and tar - and sends the archive file.

FileChute works best with a .Mac account, configuration is super easy. But since not everyone has a .Mac account, FileChute also works great with other FTP or WebDAV-accessible web server. Perform the one-time set up by following the built-in Help. Once it is properly set up, FileChute works just as perfectly with non-.Mac servers.
