File Uploader.

That is a picture that makes my life easier.

IMCE is "an image/file uploader and browser that supports personal directories and quota."

This means a quicker way to add files without going through your normal FTP manager.

You can upload image, resize them, create thumbnails or preview them all through IMCE.
You can add users, and set separate permissions for each user. There is also support for private file systems.
The basic idea of this uploader is to be able to access your files quickly and effectively. Once installed and configured, all you need to do is type in your URL and then /imce and you can access your directory.

I use it specifically to add SWF's to the database, and then access them using CKEditor SWF.

This module is quick and easy to set up, and adds some extra functionality to your site. I highly recommend it.
