Distribution
Droplets are self-contained applications (.exe or .app). If you have an established means of sending applications to an end-user, you should use that same means to send droplets.
If you wish to send a droplet to someone to whom you have not previously sent an application, the following guidelines will help ensure that droplet arrives and is usable.
File Copy
The most reliable way to distribute a droplet is to copy it onto a shared file server, flash drive, or other sharable media.
Download
Droplets can be made available for download on web, FTP, or ExpeDat servers. You should package them as a .zip first.
Email is the simplest, but least reliable way to send an application. Some email servers and security software will block or delete email messages that have applications attached. They may even do this without notifying the sender or the receiver. The following steps can be taken to maximize the chances of a droplet getting through by email.
Rename
For Windows droplets, change the file extension to something other than .exe. Let the recipient know that they will need to change it back. This is not necessary or recommended for Mac OS X droplets.
Zip
Package the droplet as a .zip file. The Mac OS X Apple Mail program will do this automatically.
Notify
Send a separate email to the receipient right after you send the droplet, so that they know it should have arrived and can check their quarantine folder if it did not.
Even with these steps, some email systems will simply not allow an application to go through, so check with the recipient to make sure they received it.
