Hi,

I have a system where the SD card can be removed and re-inserted, which collects the data without the need for restarting the arduino uno board. My aim is to get the current RTC value as the initial file name.

Please Help.

Thanks !

I didn't find the right solution from the internet.

There is no enough detail in your post to understand your issue.  Sounds like you need to read the RTC before opening the file to write and you would do this after detecting the insertion of an SD card.
