Is there any software through which I can convert my TIFF files to Notepad (text) files?
In order to convert your files, you will need an Optical Character Recognition (OCR) software. I suggest you use the SimpleOCR application. It is free of charge, easy to use and it can even recognize the handwriting. Once the converting process is completed, you can copy the text in any Notepad document. Also, you can try ABBYY FineReader, Nuance OmniPage Professional, or Free OCR to Word.
