free software to convert almost 50000 text fles to a single PDF file

Only if each letter ends (or starts) with a unique word or phrase, such as your signature or name. Then you could use 'Replace all' in Word to replace the phrase with the same phrase, but with a manual page break added. 'Find and Replace' has a 'Special' button that allows you to put a Page Break in the replacement string.

If there is such a word, but it occurs elsewhere too, you can still use 'Find and Replace', but you'd have to click 'Replace' for each page break you want, and 'Find next' when the word occurs in the middle of a letter.

Thanks very much. I never knew that we can insert page break with 'Find and Replace'. Your advice completely served my requirement. Though I have to made two world files because my pages were around 48000 and MS world said that it could handle 25000. Thanks again.
