File operations on Arduino Uno

Can anyone help me on File operations on UNO model?
I just wanted to log all the Sensors readings on a file for future use. I am bit familiar with file operation on C, but do not know how to apply them to UNO?

Your help and suggestions are greatly appreciated.
Thank you

The Uno has no file operations because it has no file system.

You can add a SD card reader to your project and do file operations on the SD card using the SD library:
That's a good option for logging sensor readings.

Thank you for the suggestion.
Greatly appreciated

You're welcome. I'm glad if I was able to be of assistance. Enjoy!
