I have to thank all of you guys. You helped me a lot. Mr. Bulia Byak, Jamie Kimberley, John Bintz and others. You are all right. The Inkscape is a great software but not for what I was trying to do. The ideas that Kimberley and Bintz gave to me was perfect. ImageMagick was the right answer to my problem. I did this: - I exported the entire SVG to a single PNG file. That gave me a file with a bit more than 19MB. - I converted the PNG in a MPC file with ImageMagick, after a long and very careful reading of its documentation. This gave me a file almost 4GB long. - Then I made a batch script, much more simpler than the other one, to export all the 29,232 parts that I needed. Amaizing, it took less than 4 hours to export all parts. I loved ImageMagick and all its powerful. I already known it, but never occurs to me that it could do the job. Thank you again, guys.
