Download the freeware 3gpToRawAvi converter from here. Then unzip 3gpToRawAvi.zip and move the folder '3gpToRawAvi' to, for example, C:\3gpToRawAvi. Follow the steps below to convert video.
1. Move a .3gp movie file you want to convert to the same folder (C:\3gpToRawAvi)
2. Click on the Windows Start button
3. Click on Run
4. Type in "cmd" and click OK to display the DOS command window

Note: Replace with the .3gp file name without the .3pg extension and with the .avi file name of your choice. e.g. "3gptorawavi Video1 -o Video2"
7. The new raw avi file will be placed in the same folder.
Note: For Windows XP and 2000, 3gpToRawAvi won't work if its folder, or any of its parent folders have a space in the name. For example, if 3gpToRawAvi is in "D:\documents and settings\" or in any folder within "D:\documents and settings\" then you'll get an error when you try to run it.
I followed your instruction, downloaded the software and save it in C:, but the error mesasges appear as shown below. Please advise what should I do to fix it.
