It could be possible that file was already open or in use. Could you please show what’s the file path?

Can you show if the File variable has a value or not @Swagasmini_Jena or try to initialize it.If you use .ToString it will throw exception if you dont have any value on it please check thanks.

cheers :smiley:

Happy learning :smiley:

If you catch the exception and then print exception.InnerException.Message you should get a more specific error message.
