Ho to add newly created .tranieddata file

[Uma Maheswara rao]

After using online font training tool for Tesseract I get  new .traineddata file. All tutorials tell me to add this eng.traineddatafile to the Tesseract-OCR\tessdata folder, but doing so, it will replace the original eng.traineddatafile. After doing this will I lose the default fonts that come with Tesseract 3.x ?

How can I Add new fonts? Its still not clear to me. I hope someone can help me here.

 Thanks.
