text file not recognized on SD card

I have been reading and writing files using SD library on Arduino for last several months.
I created a new text file on my Windows desktop and saved it on the SD Card that I have been using on my Arduino setup. When I try to open the this text file via C code on my Arduino, it is not recognized. Other files which I am reading and writing from SD card were created through C code on the Arduino and there accessibility is working fine.

The file I created on my Windows machine is a .txt. I'm guessing there is some difference in the file format and for that reason Windows created file is not recognized while other .txt created through software are working fine.

Is there something I can do so I can create files on my Windows machine and read it in Arduino?

Thanks.

First question is what you mean by "not recognised". Second question is if the filename adheres to the 8.3 naming convention.
