Loading JAD and JAR (installer packages) to your BlackBerry 7100i allows you to install the software or theme that is embedded in the file. If you want to load the files onto your BlackBerry, you simply need to connect your BlackBerry to your computer and store the files in a certain location. Once you have copied the files onto your BlackBerry device, you will be able to install the files and load the software from the device itself.

2. Browse to your JAD or JAR files on your computer, select them and press "Ctrl"+"C" to copy the files.
3. Click "Start" and then "Computer." Double-click your BlackBerry 7100i from the options.
4. Double-click the "Media" folder to enter the media card, as opposed to the "Device Memory." Press "Ctrl"+"V" to paste the files. Disconnect your BlackBerry 7100i from the computer.
