Zapr is an application that you download and install, that allows you share specific files (only the ones you select) on your computer with other people across the Internet. All you have to do is make the URL available to the people whom you want to have access to the files.
You can post the URL in a blog, or send it via e-mail or IM. Here is an example of what the URL looks like: http://zapr.net/userName/computerName/xxxxxx
The advantage to using Zapr, is that theres no file size restrictions, no need to upload the file somewhere, no sending an attachments, and finally its free. There is also no need for recipients to download and install the Zapr application or register themselves with the service to access the files.
Note: Zapr requires Windows XP with .Net Framework 2.0
